I am a descendant of Patrick Callen also. I would be his ggggg granddaughter if I have counted the greats correctly. Patrick may have had 2 daughters that died prior to the making of his will: Nellie who married James Rayburn, and another daughter-unknown- who married someone with the last name of Eires. Where can I read the Callen Chronicles? Do you know of any information about his serving in the Revolution under the detachment of Capt. John McCleland?
