This DNA project centralizes, connects, informs, & assists surname Jacobs (or variants) genealogy, & is wide open to interested members. DNA tools of autosomal & Y-DNA have clarified relatedness and lineage pedigrees tremendously. In promoting DNA testing for genealogy & trying to keep research as up-to-date as possible, we follow the ISOGG (International Society of Genetic Genealogy). Expectations are 1. to provide name & a date of an earliest surely-known ancestor in your line, 2. to maximize connectedness with an autosomal test, then put in Gedmatch.com so not limited to one testing company, 3. to attempt maximized Y-DNA testing on a male in each distinguishable lineage, & 4. to support others' DNA testing for genealogy. DNA branches were established 7000 years ago &1000 years ago surnames were invented. The surname Jacob(s) was given to someone with father, grandfather, or earlier male ancestor. We'll find Jacobs who aren't related & close paternal relatives with different surnames. <https://en.wikipedia.org/wiki/Jacobs_%28surname%29> To ensure the accuracy of the project database those who have tested with labs other than FTDNA must forward their results (pdf file, etc) to a project administrator prior to being added to the project.
