Brandon, I can tell you that in those books you will find no primary evidence of who Robert Abell's children were, apart from Mary.And I'm not putting you through hoops to be mean.
Neither Horace Abell, Carl Boyer III, or Richmond heralds past or present have proof of the identities of the other children of Robert Abell.Why?Because the records in Rehoboth that would have provided that information are lost.They don't exist.
You can curse the fates, but in all the decades of meticulous searching (and any genealogist can appreciate the hard work involved), nobody has located those records.The Abell family was literate, and maybe some day, for instance, a letter will surface naming these children.Never say never.It's amazing how much stuff is out there.Right now there's a project underway to translate 12,000 (!) pages of documents pertaining to the colony of New Amsterdam.
From the 1880s through the end of the 1930s, a lot of family histories were written, and some of them are good, and some aren't.The United States is now, if you include the colonies, about 400 years old, but if you've ever journeyed to Britain and stood in a structure like Westminster Abbey, which was built in the 13th century, 400 years doesn't seem like all that much.
Americans love to connect with some old family in Britain or Scotland or Ireland.I had one relative (now deceased) who traveled to Britain and met a peer, thinking she was related to him, when in fact as far as I can tell, she wasn't related to him at all.And yet, if you questioned her on it, she'd tell you it was all well documented in the book she wrote, but of course it wasn't.
Realistically, my relative was deluded, and she was deluding others.I don't think she was a con artist.But that's not good—her book was quite expensive.You have to start from where you are, and right now, the paper trail ends in Rehoboth.
Maybe some day a new trail will appear.I hope it does.
