I administer a Crates DNA Project established with FTDNA in Houston which seeks to compare Y-DNA samples from living male descendants to indicate familial relationships with persons in so-far unrelated groups. Because of name variations even within documented known families, the project seeks to cover similar names, especially Crates, Creates, Crate, Grat. Gratt, Greth, etc. Anyone with like names is invited to participate, either by making contact through FTDNA or through me here.
