Reverend Francis Segrave born 1654 Ireland- died Jan 1725-27? Isle of Wight County, Virginia. Married to Lucretia in 1685. His occupation was minister, and appears in many important papers such as wills as a witness.
He is the common ancestor to all Seagraves in the south, with all various spellings of the name. Through his son William Segrave who had three wives and thirteen children, his descendents have spread through North Carolina, Georgia, and Tennessee.
For more infromation: Sandra S. Day wrote the book Reverend Wm. Segraves & his descendents, but unforntunately it is out of print. Maybe if you live in the south you could find it in a county library, good luck & good hunting.
