The purpose and goal of this project is to determine possible relationships between the various Philbrick/Philbrook lines around the world. By using a simple DNA test we hope to find out which Philbricks, Philbrooks, Felbriggs, Fylbriggs and others with a similar surname have a common ancestor. We may also be able to help place a Philbrick of unknown ancestry into one of the Philbrick lines that we have identified so far.
