Bob, I just dropped into this story and may be an extremely distant cousin. It's a long shot but it's possible Jacob b. 1774 may have a birth record in the Edenderry Quaker Meeting Minutes. Here's what's available: Edenderry, births, marriages and deaths up to 1859, Library of the Society of Friends, Dublin. Also National Library Positive (microflim) 1022; 1612 1814 (in the form of family lists), National Library Positive (microfilm) 5531. You could order the films at a local LDS center and see. I believe Jacob's maternal grandmother may be a Sarah Chandlee b. 1703 who 1st married a John Eves and 2nd a Samuel Pierson. These people were Quakers in the second half of the 1600s to mid-1700s (at least) and some of them I know were attending the Edenderry meetings. By the later 1700s, the families may have no longer been practicing Quakers but it may be worth checking. Ballyhagan in Co. Kildare is near Edenderry and the near locations I have associated with these people I mentioned. There are Quaker marriage records for the Ballyhagan, Co. Tryone meetings but doesn't look like much else.
