Please help.looking for James Hamilton Stewart b 1805 and wife Mary Johnson Stewart b circa 1815 from County Down. Later moved to Jefferson County, Pennsylvania.

I'd need more information to be able to definitely say that this is your ancestor, but the fact that the father is 'Hamilton" may be a clue.

This transcription is from rootsireland. James Stewart was baptized in the COI on 23 August 1805 in parish of Donaghadee; parents Isabella and Hamilton Stewart.
