Andrea,
I added Isom and his 1st cousins to the 1776 project and added the above sources to their profiles.
Do not worry about Orphan profiles so much if they are connected to the family tree.
While thier profiles can always be improved, having them connecte and sourced is very helpful. If you wish to adopt them to update their profiles, by all means do so, but you do not have to keep them and you can leave them without a Profile Manager when they are connected and sourced.
Thanks again for finding and helping them get connected.
