Your Gaelic is better than mine but I get the drift . . .
No, this Gordon is not the astronaut - different Fullerton lines.(That was a common question some years back when people still paid attention to the space program.)I think this Gordon was an accountant of some sort - he always shut down his genealogy work as tax day approached.
If you cannot locate a copy of Gordon's "Fullertons of NA" compilation, you might try reaching the person to whom Gordon handed the project. I just dug up his name - Baird Fullerton - who lives somewhere near Phoenix AZ.The last email address I had for him is (please replace the "at" with an "@" and the "dots" with a "."in the address)You can also Google the name to find his address.
