The goals of the Dawbarn DNA project:-

Are the three known families of Dawbarns linked?

Y-DNA results will show the direct male lines back further generations than autosomal tests and could bridge gaps in the paper records.

Are there DNA links to the Dawborne surname and other variants?

Discover information which may solve research problems, and/or resolve brick walls

Discover information about the evolution of the surname

Preserve DNA results for future research, to protect against any male line becoming extinct
