John, I just sent you a detailed email. We may be connected although the oldest members of the family think that if there were Brennan relatives in PA that my Great Grandfather Daniel Brennan, son of Philip, would have found them and maintained contact.
On one occasion he personally hired the Pinkerton Agency to come from Philadelphia to Shenadoah to determine who committed a theft. Given his resources and ability to get things done, it seems odd that he might have had uncles living in PA and not been in touch.
I sent you what I have as a file attached to the email.
