Christopher, I didn't do the research and I suspect that some of the "abt" dates were not based on subjective imformation, only estimations on someone's part. I am suspicious of some of the places. They may have been assumed. Your imformation about the emigration date of 1765 would explain why I only have children born after that date. Surely there were children born before he came to America, but some or all of the children would have been old enough to stay behind or come on their own. Susanna may have been a second wife and probably much younger. Having children at 47 is not so unusual even today and we don't know that she was 47 as her birth year is one of those "about" dates as well. So that leaves us where we started. I, too, would like a lot more imformation concerning this family.
