Genetic markers can be used to trace a family lineage, developing a potentially different, or more expansive, family history than that reported by individuals. The Sorenson Foundation is collecting genetic profiles to aid genealogical research. Here’s their program description:
The Sorenson Molecular Genealogy Foundation (SMGF) is a non-profit organization committed to developing the world’s foremost database of correlated genetic and genealogical information, and making this information freely available to the public.
