Find a family connection
Two names, two families: is there a path between them? Measure the kinship, with evidence to support it.
Many Jewish families know themselves to be « a little cousins » without being able to prove it. By linking trees submitted to documented lineages, Zakhor seeks the shortest path between two people or two families — and asserts a link only when a chain of sources supports it.
How it works
Two starting points
Indicate two people, or two lineages: an ancestor from your tree and a documented family, or two names to compare.
The shortest path
The common tree is searched to find the closest shared ancestor, and the degree of kinship that follows from it.
Sources to back it up
Each link in the chain refers to the document that grounds it. A link that is only « probable » is displayed as such, never presented as certain.
Automatic kinship search is under construction. From now on, you can import your tree and explore lineages to prepare the comparison.

This tree grows with you
The genealogy of the people is a collective work. It calls for three commitments, open to all — no account needed to begin.
Contribute content
A GEDCOM tree, a ketouba, a rabbinic deed, an oral tradition about your origins: each item you contribute can unlock research for ten other families.
