I think that Willemtje Morren who married Willem Hop is the sister of my great-grandmother Aaltje. I have a bunch of odds and ends, inclding photos I took at Beaverdam cemetery last year, but that line has gone on the back burner. I spent my last trip (over Memorial Day) at Graafschap cemetery (other side of the family).
I do have Jacob Hop and Aaltje Mulder in my database of a boatload of Hops, but as far as I know they are not related to me (at least not back to about 1780)

Oh, and yes, I did go to The Netherlands - 3 years ago already now! I went with my daughter, we did a little of the tourist things and a lot of just driving around family locations in 5 provinces. But we did not do any research or try to contact any potential family. Next trip! (We did stay at a nice B and B in Harderwijk)
Sorry, I don't do this stuff often and am unfamiliar with the site!! But I see now the message I wrote about 15 minutes ago - at 8:0 pm, is posted here below at 6:46. So that explains why you thought I was at work so early!

Sorry for a late reply. I've been busy working on a friend's family and have not been looking here!! I'll work on getting a report run of the descendants of Jacob and Aaltje that I have recorded and send that to you, I will be in Michigan again in September, but only briefly in Holland.
