IGUD HAKOHANIM REGISTRY

Kohen Registry & Lineage Intake

Igud HaKohanim maintains a growing registry and lineage intake system for Kohanim, Kohen families, and individuals with a possible Kohen lineage. Its purpose is to preserve priestly lineage, strengthen responsible communal recognition, and build lasting infrastructure for the descendants of Aharon HaKohen.

Register Your Kohen Lineage or Connection

Registration is open to confirmed Kohanim, those with possible Kohen lineage, family members of Kohanim, Bat Kohen, Eshet Kohen, community members with relevant testimony, and interested supporters who wish to stay connected to the work of Igud HaKohanim.

Submitting the form does not by itself establish vetted Kohen lineage. It begins an intake process through which information can be preserved, organized, reviewed, and, where appropriate, followed by requests for additional testimony, records, lineage information, or other supporting evidence.

Why Register?

A responsible registry helps preserve family tradition, document known Kohen families, support future lineage review, and help Igud HaKohanim remain connected with Kohanim and Kohen families for Torah, educational, communal, and priestly needs.

Who May Register?

This intake is not limited to someone who is already certain that he is a Kohen. Anyone with a serious connection to kehuna may register and help preserve information that may prove valuable to a family or lineage in the future.

Kohen by Tradition

A man known in his family or community as a Kohen through paternal descent from Aharon HaKohen.

Possible Kohen Lineage

A person whose father, paternal grandfather, surname, family memory, or community background suggests possible Kohen lineage.

Kohen Family Member

A Bat Kohen, Eshet Kohen, relative of Kohanim, or family member who wishes to preserve information about a Kohen family line.

Community Testimony

A rabbi, community member, researcher, relative, or other person with relevant knowledge of a Kohen family, synagogue practice, or communal tradition.

Intake Is Not Verification

Registration and vetting are not the same. Initial registration allows Igud HaKohanim to receive information and begin preserving a lineage record. Vetted registry status requires additional review.

Kehuna is a Torah status inherited through the paternal line from Aharon HaKohen. It is not created by filling out a form, joining a registry, carrying a particular surname, presenting a single document, or receiving a genetic result.

Family tradition, community recognition, testimony, documented practice, historical records, paternal genealogy, and modern supporting evidence can all contribute to a stronger lineage record when examined together and with appropriate care.

FROM INTAKE TO REVIEW
PROJECT MALACHI™  •  PATENT PENDING

Our Patent-Pending Lineage Verification Framework

Igud HaKohanim is developing Project Malachi™, a proprietary, patent-pending lineage evidence and review framework designed to support responsible registry development and future recognition of well-supported Kohen lineages. Its purpose is to organize, preserve, compare, and strengthen the forms of evidence that bear on paternal priestly continuity.

Review may include the claimant’s known father-to-son lineage, family tradition, communal recognition, synagogue practice, testimony from relatives or community figures, family documents, cemetery and historical records, and other supporting material.

Where relevant, Y-DNA and other paternal-line genetic evidence may also be examined as one supporting component of the larger record. Genetic evidence does not stand alone and does not replace the family, communal, documentary, and Torah evidence surrounding a lineage.

For those seeking high-resolution Y-DNA testing, Igud HaKohanim refers Kohanim to the Big Y-700 test from FamilyTreeDNA.

PRESERVATION, PURIFICATION & CLARIFICATION

Preserving the Record Toward Fuller Clarification

The work of a Kohen registry is not merely administrative. Preserving paternal lineage, family testimony, communal memory, records, and supporting evidence serves a larger Torah purpose: maintaining the identity and continuity of the descendants of Aharon so that priestly lineage can be approached with seriousness, responsibility, and readiness.

MALACHI 3:3
וְיָשַׁב מְצָרֵף וּמְטַהֵר כֶּסֶף וְטִהַר אֶת בְּנֵי לֵוִי

Malachi describes a future purification of the sons of Levi. For Igud HaKohanim, that vision gives broader meaning to the careful work of preserving and clarifying priestly identity.

EZRA 2:63
עַד עֲמֹד כֹּהֵן לְאוּרִים וּלְתֻמִּים

Ezra records a case in which priestly families whose genealogy could not be established were held apart from the most sacred priestly foods until a Kohen would stand with the Urim and Tumim.

Igud HaKohanim does not claim that a modern registry replaces that ultimate standard of clarification. Our task is to responsibly preserve what can be known now: paternal genealogies, family and communal testimony, historical records, documented priestly practice, and relevant supporting evidence. The registry preserves that record in preparation for the fuller clarification envisioned by the words of Malachi and Ezra.

Registration May Allow You To

Preserve Family Tradition

Preserve your family’s memory of kehuna, including paternal lineage, names, places, community background, customs, and known practice.

Support Future Review

Begin an intake path that may support later lineage review, documentation, and, where appropriate, vetted registry recognition.

Receive Updates

Receive occasional information about educational resources, registry development, matnot kehuna, and matters relevant to Kohanim.

Be Available for Mitzvah Needs

Where appropriate and with consent, be available when a family or community seeks a Kohen for a relevant Torah or communal need.

Pidyon HaBen Support

Request access to Igud HaKohanim resources for Pidyon HaBen ceremonies you perform or help arrange.

How Registration Works

After you submit the form, Igud HaKohanim may review the information and, where appropriate, contact you for clarification or follow-up.

Depending on the submission, later steps may include recording additional paternal-line information, requesting family or community testimony, reviewing documents and supporting records, comparing historical information, or discussing Y-DNA testing where it could contribute useful paternal-line evidence.

No public claim of vetted Kohen status is made merely because a form has been submitted. The purpose is to build a serious and responsible registry that preserves Kohen identity with care, dignity, continuity, and appropriate review.

Privacy and Discretion

Information submitted to Igud HaKohanim is handled with discretion. Personal information, family history, lineage records, and supporting materials are not intended for public publication without appropriate consent.

Some registrants may wish to be contacted for mitzvah, educational, communal, or lineage-related purposes. Others may prefer only to preserve their information privately. The registry is designed to accommodate these different needs responsibly.

    Support the Malachi Fund

    The work of preserving and clarifying kehuna is not only an administrative project. It is part of a larger Torah vision: to help restore dignity, clarity, and readiness to the families of Aharon HaKohen and Levi.

    The prophet Malachi speaks of a future purification: וְטִהַר אֶת בְּנֵי לֵוִי — “He will purify the sons of Levi.” In that spirit, the Malachi Fund supports Igud HaKohanim’s work to build responsible infrastructure for Kohanim, Kohen families, lineage intake, registry development, education, and future Torah-based preparation.

    If you value this work and wish to help strengthen it, we invite you to support the Malachi Fund. Every contribution helps us continue building carefully, humbly, and with respect for the sanctity of kehuna.
