I am on the trail of my Decker/Dekker ancestry. Genetic matches increasingly suggest I'm descended from Jan Gerritsen Decker (1662-1740) of Gelderland but the picture is fragmented and the jury is still out. My brick wall is my Gx2 Grandfather, James H. Decker. He fathered my Ggrandfather, John H. Decker, out of wedlock in 1869 with Dorinda Odell in Warwick, Orange county, NY. Several candidates for James H's identity and patrimony, but none with paternal information linking them up to my genetic matches. I was born in Springfield MA and live in the Netherlands these days, so have the opportunity to visit the very buildings my ancestors walked, could I but find the thread! Among the Dutch names that appear commonly among my matches that I am actively investigating: Hornbeek, Tietsoort, Van Etten, Oosterhout, Roosa, Ten Eyck, & Terwilliger.
