John Collins' father was named James; AFAIK, John Collins did not have a sibling by any of those 3 names and his wife was Mary. Children were named Benjamin, Hugh and Mary - so it is likely that you are not a direct descendant. BUT, they were large families and for all you know James Collins' - John's father - might have had a sibling or other relative who is your ancestor. Worth digging into it IMO.As far as I can remember my grandmother spoke of 3 family members from Ireland. App, Cora, and Charlie Collins.That would have been a great discovery to add to my family tree.
