I just recently set up a Blocker / Blocher DNA project at FAMILY TREE DNA:http://www.familytreedna.com/(anrz00455pf4qyegfgckb1rq)/ftGr...
The main goal of this project is to prove or disprove that the BlocKer family of America descends from the BlocHer family in Germany. We have been at a brick-wall for a hundred years on this issue, trying to find the illusive immigrant, or merely determine which country the Blockers here descend from.
Some of us now believe that the first Michael Blocker (circa 1735 N. Carolina) was deliberately mis-listed as "Michael Blesser" who came over on the Ship Alexander and Anne, William Clymer, Master. September 5, 1730, into the port of Philadelphia.
There are numerous arguments that have led to this theory, so that we now believe this "Michael Blesser" to really be Michael Blocher, son of Georg Blocher and Maria Kapler, or at least from their basic Blocher family, and descended from Georg's ancestors somewhere. (This would include the Blocher/Wegengast marriage) You can check out the notes compiled here:http://wc.rootsweb.com/cgi-bin/igm.cgi?op=GET&db=bevange...
All we need is a male Blocher who believes they are descended from either Georg and Maria Blocher, or Jakob "Hans" Blocher and Anna Zetzel. I will pay the cost of doing a 12 marker test, which would point to a precise common male ancestor 300 years or more in the past.
PLEASE write me as soon as possible if you are, or know of, a willing Blocher candidate. This project will also help prove or disprive all families believe to related in the basic group of Blocher / Ploeger / Blucher / and Blocker.
