Do you know anything about Jacob and Barbara's son Isaac who was born about 1764, so probably in West Manchester, but that's what I'm trying to prove? My ggggg-grandfather was Isaac Almons/Almonds/Amond/Ammons (he probably couldn't spell) of Greene Co., PA, and I think the Isaac Ammon who is the son of Jacob and Barbara Ammon may be him, as they are the most likely suspects, and Jacob's will From Washington Co, PA mentions a son named Isaac. Isaac died December 1820 in Whitely Township, Greene Co., PA. He is also listed in late 1700s tax records as owning land in Bedford Co., which is between York and Washington/Greene Counties.
