I did see that, but I think it muddies the waters a little more.
Our profile for Robert says he was b. 1626 Virginia - d. 1697 Virginia to Welsh parents. The Betty Meischen Genealogy.com tree we're citing says Robert's father was Scottish and that Robert was b. 1650. Meischen also says on Elinor's profile that Robert was actually b. 1662 in/of New Jersey. So I think that whole tree isn't reliable and we should probably not be citing it. (In her citations, she's largely relying on Ancestry trees.)
For Meischen's self-published book, we have the same issues again, of course. The book also constantly self-cites, and even finds a way to cite The Hiram Key: Pharaohs, Freemasons and the Discovery of the Secret Scrolls of Jesus. !!! (I do admittedly respect the citations attributing "Unknown source," however.)
Can any managers weigh in on whether you've found better sources, outside of Meischen? If not, I'll do some digging later today.
WikiTree goes with "parents unknown," which might be our solution here.
