Peregrine White, "Mayflower" Passenger - Y-chromosomal DNA

Normally I'd suggest using the Lists feature to pull a list of descendants with claimed Geni profiles. In this case I think there's a limit with lists that won't search beyond a certain number of generations. A search doesn't even pull up you as a descendant, but Geni does show the direct relationship.

Mike Stangel - Can you fill us in on that limit?

Good question, Jonathan Scott Krengel! There's a performance limitation on how much of the tree we can search in the amount of time that you're waiting for the web server to respond. The limit is on how many profiles we search, not how many results (e.g. claimed descendants) we find. For the list views and most other places, we search 5000 profiles. For descendants, that means all of the children first, then all of the grandchildren, then all of the great-grandchildren ("breadth-first" in computer science parlance) until we've found 5,000 profiles and then we stop. If you're descendant #5001, you won't show up on the list.

Out of curiosity I had to check where Private User shows up -- descent number 8,940!

Mike Stangel - Hmm, background job reports could be a nice Pro feature.

Eleventh generation. If every descendant managed an heir and a spare, there's over 2000 unbroken male-line descendants in my generation. I don't think Geni can search for direct male-line descendants. Let's assume, then, three children. We're most of the way to 200,000 people in my generation. Peregrine likely exceeded 5000 descendants around the eighth generation, or my great-grandparents' generation. Of course, not all descendants are going to be in Geni, but a good many will among a group so well-researched as this.

I was hoping the prominence of Peregrine White being (born) on the Mayflower would mean that the Y-chromosomes of some substantiated descendants would have been genotyped.

Knowing whether the Geni collaborative might be right or can't be right would make a difference in how I approach the research.

So it's still possible. It just means you have to break it out and use each of the direct male line grandsons of Peregrine as starting points. This may not reach all claimed descendants.

Mike Stangel - Could the list feature tell us if it had completed the search or reached the limit? This would be helpful information.
