I am glad to see you here. I have been searching everywhere, as you know, for the same information on Hugh's parentage. I have corresponded with Judy Henry and she sent me the following info, though you may already have it.
"David Henry will know if we get any results connecting Hugh to Alexander Henry in the little research project that several of us are having done in Scotland. My Henry family is Samuel, Sr. of Washington Co. NC/ now Tennessee. He had a son Hugh - and I have followed your Hugh pretty closely to try to keep their records separate. Good luck with your searching. You have collected wonderful information."
By the way, did you know that W. Alexander Henry, of Kentucky, died April 5, 1999? He was such a help to me and others. He will be missed.
