The Igud HaKohanim Standard
Igud HaKohanim’s DNA and genealogy research forms part of Project Malachi™, our patent-pending lineage evidence and review framework. The framework is designed to organize and preserve the different forms of evidence relevant to paternal-line research while keeping genetic evidence within the larger family, documentary, communal, and Torah record.
Commercial laboratories produce genetic data. Genealogical platforms organize matches. Igud HaKohanim evaluates that information within the fuller record of Kohen paternal descent and provides its own priestly-lineage assessment of the evidence presented.
Our direction is clear: a Kohen seeking serious paternal-line verification should register his line, consider completing the Big Y-700 test, document his known father-to-son ancestry, preserve the complete result package, and submit the evidence to Igud HaKohanim.
Every Kohen is encouraged to register, including those who have not yet completed testing. Genetic results, family testimony, and supporting documents can be added to the lineage record as they become available.
DNA Supports the Lineage Record
Kehuna is a Torah status transmitted through the paternal line from Ahron HaKohen. Y-DNA examines biological paternal continuity. It does not create Kehuna, replace inherited priestly standing, or independently determine the complete standing of a family line.
Paternal Continuity
The Y chromosome passes from father to son and preserves evidence concerning the direct male line across generations.
Family Corroboration
High-resolution results may connect paternal branches, support a documented relationship, or reveal a shared male ancestor.
Priestly Evaluation
The result is considered together with family testimony, paternal genealogy, synagogue recognition, ketubot, gravestones, historical records, and inherited Kohen tradition.
THE PRIESTLY STANDARD OF COMPLETE CLARIFICATION
עַד עֲמֹד כֹּהֵן לְאוּרִים וּלְתֻמִּים
Until a Kohen Stands with the Urim and Tumim
The gold and silver shown in this image are not decorative inventions. They come directly from Malachi’s prophetic description of the purification of the sons of Levi. The prophet describes a refiner and purifier of silver who will purify the sons of Levi and “refine them like gold and like silver”. The gold and silver in the artwork therefore visualize Malachi’s own imagery of refinement, purification, and the preparation of Levi for sacred service.
The conclusion of the verse explains the purpose of that purification: “and they shall be for the LORD bearers of an offering in righteousness.” The image therefore presents refinement not as an end in itself, but as preparation for restored and properly ordered sacred service.
Alongside Malachi’s vision, the artwork incorporates Ezra’s description of unresolved priestly lineage awaiting complete clarification: עַד עֲמֹד כֹּהֵן לְאוּרִים וּלְתֻמִּים — “until a Kohen stands with the Urim and Tumim” (Ezra 2:63). The image is an artistic representation joining these two scriptural themes; it does not depict an actual Igud HaKohanim ceremony.
Ezra places the complete resolution of uncertain priestly lineage with the Kohen standing with the Urim and Tumim. The Kohen described here is the Kohen Gadol, the priestly head entrusted with Mishpat HaUrim.
Ezra’s wording places this clarification within the priestly institution. The Kohen does not merely witness the process; he stands with the divine priestly instrument through which an unresolved lineage is brought to completion.
The Mishnah likewise preserves an internal priestly process in which the lineage and fitness of Kohanim entering sacred service were examined. Present-day documentation continues the practical work of preserving the record, gathering the available evidence, and preparing a foundation upon which fuller clarification may one day stand.
The Rambam places this clarification within the broader restored order of the future era, describing the descendants of Levi as the first lineage body to be clarified. His formulation complements Ezra’s description of a restored national order in which priestly and Levitical lineage is ultimately brought into clarity through divine guidance.
The 24 Mishmarot
The Kohanim were organized into 24 priestly divisions. These mishmarot represented distinct paternal houses within the descendants of Ahron HaKohen and provide an essential framework for understanding the historic structure of the Kehuna.
SIXTEEN PATERNAL HOUSES
The Descendants of Elazar
Sixteen of the 24 mishmarot were established from paternal houses descending through Elazar, son of Ahron HaKohen.
The larger number reflected the greater number of recognized paternal family heads found among the descendants of Elazar when the divisions were arranged.
EIGHT PATERNAL HOUSES
The Descendants of Itamar
Eight of the 24 mishmarot were established from paternal houses descending through Itamar, son of Ahron HaKohen.
Together, the 16 houses of Elazar and the 8 houses of Itamar formed the complete system of 24 priestly divisions.
The 24 mishmarot demonstrate that the Kohanim include multiple historic paternal branches. Assignment of a modern Kohen to a particular mishmar requires evidence connecting his paternal line to that historical house; it cannot be established from a surname or broad haplogroup alone.
A SELECT AND DISTINGUISHED PRIESTLY LINE
The Kohanim, Sons of Tzadok
Among the descendants of Elazar, the sons of Tzadok hold an especially distinguished place within the priestly lineage. The prophetic record identifies them for their fidelity to the sacred service and for their particular standing in relation to the future Temple.
Igud HaKohanim invites Kohen families that preserve a paternal tradition, historical record, geographic connection, or other relevant material concerning possible descent from the sons of Tzadok to register and preserve that information for responsible study.
No surname, haplogroup, isolated genetic match, or family claim establishes descent from Tzadok by itself. Such traditions deserve careful preservation, but any conclusion must be approached cautiously and supported by substantial evidence.
Preserving family traditions and historical materials concerning possible surviving lines of the sons of Tzadok is an important objective of Igud HaKohanim.
Why We Direct Kohanim Toward Big Y-700
Older low-marker tests may indicate a broad paternal pattern. Big Y-700 provides the resolution needed to examine the finer branching of a Kohen family’s direct male line and preserve information that gains value as more Kohanim test.
01
Terminal SNP
Identifies the tester’s presently defined position on the Y-chromosome paternal tree.
02
Branch Placement
Helps distinguish related paternal branches and identify where family lines divide from their closest tested relatives.
03
Private Variants
Preserves newer paternal mutations that may define family branches as additional relatives complete testing.
04
Long-Term Research Value
Creates a durable paternal-line record that may become more informative as genetic science and responsible family research continue to develop.
The Proper Scope of Y-DNA
What Y-DNA Can Establish
- Whether two tested men are consistent with descent from a shared paternal ancestor
- Whether documented paternal branches belong to the same genetic line
- Where a direct male line is positioned on the current Y-chromosome tree
- Whether a result contributes useful information to broader paternal-line research
- Whether an assumed paternal relationship is genetically incompatible
- Whether testing additional paternal relatives would clarify the family structure
What Y-DNA Does Not Establish by Itself
- It does not create Kehuna in a family that does not possess it
- It does not reconstruct the priestly standing of every generation in the paternal line
- It does not identify Ahron HaKohen’s personal genetic result
- It does not establish descent from a particular mishmar without connecting evidence
- It does not establish descent from Tzadok through a haplogroup alone
- It does not turn a commercial certificate into a complete priestly-lineage determination
Biological Descent and Priestly Standing
A Y chromosome may continue through a biological paternal line even where the priestly standing of a descendant has been affected. A man may therefore carry a paternal line originating among Kohanim while being a chalal.
A laboratory result addresses biological paternal ancestry. It should not be treated by itself as a ruling concerning a person’s Torah or priestly status.
A DEVELOPING INSTITUTIONAL PROGRAM
Responsible Preservation and Research
Igud HaKohanim is developing a responsible institutional program for preserving paternal-line records and supporting careful research concerning Kohen and Levi families.
This public page explains what participants may submit and the general purpose of the program. It does not describe Igud HaKohanim’s internal research procedures, analytical tools, comparative datasets, or decision criteria.
Registration preserves information for study; it does not by itself certify lineage, determine Torah status, or guarantee a particular research conclusion. The program may continue to develop as additional records become available and genetic science advances.
Register the Families of Sacred Service
The preservation of lineage concerns both Kohanim and Leviim. Kohanim carry the priestly service and instruction entrusted to the descendants of Ahron. Leviim serve within the Mikdash order under the charge and direction of the Kohanim. Both paternal bodies belong within the restored structure of sacred service.
KOHEN LINEAGE
Register a Kohen Paternal Line
Kohanim, possible Kohanim, Bat Kohen family members, and families preserving relevant testimony are encouraged to begin a lineage intake and select Kohen within the form.
LEVI LINEAGE
Register a Levi Paternal Line
Leviim and families preserving a paternal tradition of Levi descent use the same lineage-intake form and select Levi within the form.
Both buttons open the same lineage-intake form. The registrant selects the appropriate Kohen or Levi option within the form.
The Lineage Submission Path
Begin by registering the paternal line. Where appropriate, complete high-resolution Y-DNA testing and construct the family record around the strongest available evidence.
STEP 1
Register the Paternal Line
Open the shared intake form, select Kohen or Levi, and enter the known direct paternal ancestry.
STEP 2
Complete Y-DNA Testing
Where possible, test the appropriate living representative of the direct paternal line and retain the complete reports and downloadable files.
STEP 3
Submit the Evidence
Add the Y-DNA results, paternal genealogy, family testimony, records, geographic history, and relevant lineage traditions.

Privacy, Consent, and Preservation
Genetic and family-lineage records are sensitive. Igud HaKohanim receives these materials for priestly and Levitical lineage preservation, comparative evaluation, registry administration, and responsible institutional documentation.
A person submitting information concerning another family member or a minor must possess appropriate permission to provide that information.
Medical interpretation is outside the purpose of this program. The review concerns paternal genealogy, family continuity, and the preservation of lineage evidence connected to sacred service.
