That's true about the conjecture on this board and others. I have a Johann Nicolas Milliron married to a Shusy (Susie)Beighley and according to one researcher Johann Nicholas and Anna Catherina are half brother/sister.
Johannis Beighley could also be Johannis CONRAD Beighley who married a Catherine (no maiden name), but they have no daughter named Susanna. If you want to trade info, e-mail me at: firstname.lastname@example.org
