A tricky puzzle. My great-great-great-grandfather was George Lemon of Creeverow (circa 1783-1818). His father may have been born around the 1750s, and grandfather in 1720s. So the latter could appear in the Armagh Presbyterian baptismal records (1707-28). Firstly, what was George's father's name? According to our family tradition it was Pooler. But, if this is not right, then it might have been William, Robert, John, George or other - in that sort of order of probability. This conjecture is based on the pattern of names given to George Lemon's descendants. Secondly, trying to calculate his grandfather's name is even more difficult, but, looking at the baptismal records, possible candidates are John b.1726 or George b.1728. All so much conjecture, I'm afraid.
I would like to share any information on Leeman ancestors, preferably more solid evidence than I came up with here!
