I know this is an old post, but I hope you are still searching. I too am searching, for a friend. My ex daughter in law is a descendant of Hubert Laah Allen. I have learned a lot from your posts. If you have new information please email firstname.lastname@example.org
Someone on ancestry has the mother of Hubert married a second time to a Francis Coley Guy. I cannot find that record yet though.
Let me know what you have found.
