GRANDMA is the acronym for The Genealogical Registry and Database of
Mennonite Ancestry, a project of the California Mennonite Historical
Society. The current version (#7) of the
database has genealogical information for over 1.2 million individuals whose
ancestral lines trace back to Mennonite communities in Poland and Russia.
The database can be accessed
through online subscription or purchased as CD-ROM through the California Mennonite
Historical Society website.
