Re your posted message 2/9/2002, Dianne, Henry and Jennet Atherton did have a daughter named Grace. She was the first of their five children, but she was born in England (probably Lancashire) bet. 1678-1690. She was the first of the family to immigrate to Pennsylvania and she married Dr. Richard ap Thomas 1/15/1712/13 in Whiteland Twp., Chester Co., PA. He was son of Richard ap Thomas in Whitford Garden, Flintshire, Wales. She doesn't sound like a match for your Grace. Keep hunting!
