We have an issue like that. we swear something happened to an Aunt of ours. She had 2 children out of wedlock and wonder who fathered them. Might be a family member. The records are sketchy on the issue. I havent asked around to see what anyone may know. I left it off the tree so no one gets mad at me for "Assuming" though other cousin researchers have questioned the same thing I do on the issue.
