Re: William Lowman, d. 1788, Philadelphia
My hubby is a Lowman/Lorman descendant from Samuel & Letitia Wood Lowman. They were married 14 JUN 1716. I have three sons for them:
1) Joseph b: 1717 in New Castle Co., DE
2) Samuel Jr. b: 1718 in New Castle Co., DE (This is my hubby's line)
3) William b: 14 Sep 1719 in New Castle Co., DE
I don't have parents for the elder Samuel, so your guess is as good as mine, right now. Our line eventually changed its spelling to Lorman & headed to Philly. Hope this helps.
