HI Cowpoke,
I'm Bill Feller. I'm from S Dakota. I am not blood related(guessing you are Gene), but if your dad was a natural son of Martin Forret, then you and I would be 3rd cousins. My gr-grandmother Magdalena Forret Feller was a sister of Martin's father John Forret. If you are interested in the Forret lines, I could tell you quite a bit.
Until now, I have only had William and David Harrelson on my family tree. I also had Wm & David Forret. Realizing they were stepsons, I deleted them as Forrets, but keep them as Harrelsons. I still keep step children and families on the tree. .....The Forrets in Iowa still have a family reunion annually outside Des Moines. They try to add all births, marriages, & deaths every year. Aside from that, I have my own family tree that includes all the Fellers(Magdalena Feller was the only Forret daughter who had children). I have over 7,000 descendants(including spouses) on my tree.
I realize this is an old message thread, but hopefully still followed.

Bill
