We needn't get too excited over this project which is only a "partial" list of 'Gateway' ancestors strictly limited to people with Early American ancestry.
Every European country should (and probably do) have their own, completely separate list for anyone interested in their ancient genealogy. Let's locate and make projects out of them, too.
I was a little surprised (and delighted, for sure) to find at least one of my gateway ancestors on this partial list, and find it fairly helpful. However, the partiality of the list is a bit concerning. It would be great to know that genealogists are seriously working on expanding the list for the sake of completeness and accuracy, as I am reasonably certain there would be more among some of my lines (assuming they are properly proven, of course).
Although not a 'joiner' myself, projects like this are fun and can be educational, imho. I appreciate it very much. Would like to see similar ones for populations other than American, as I suspect they do exist.
( Sharon Doubell that anti-virus hopefully doesn't interfere too often with your online research, that would be terrible.)
