Sherburl, thanks for the screenshots, that was helpful. I don't know if it's having Jewish ancestry that means I'm not getting the hints (we have a harder time with paper trails past the mid-19th century) or just dumb luck, but I haven't seen any hints yet. For the regular Ancestry side, yes, lots of them, including a few potentially shared family trees (some that are correct even).
As for the phasing argument elsewhere in this thread, I've seen it discussed at length and the consensus is no, it's not happening. After all, you can't phase individuals. You can only do it if you have at least two people in a known relationship to each other where they don't share two parents. The ideal set of people to phase is one person with each of his or her parents.
