Isabella Downing is in my family tree...I don't have time to write right now...but if I forget email me. Twyla Edwards Holloway I have Holcombe, Davenport, Mills, Westmoreland Married a Lassiter, he died. but the one that may be in your family tree is the Holcombe branch. Thomas Holcombe from Wales. It could just be a coincendense that Isabella Downing showed up so much later....I have her back in the 1400's I think, just off the top of my head. I'm a geneology geek too.
