Deann,
I think that the Mary Embler that married Peter Wortman was the daughter of William Emler/Embler of Rowan, NC and the sister of William Imbler who married Frances Sears.
In Rowan Co., NC Deed Book 26, page 172: 25 Oct 1817. John Embler Sr, Phillip Wortman, John Wortman, Isaac Morris & wife Susan and George Workman (as heirs of deceased William Embler of Rowan Co., NC) let Andrew Byrns of Rowan Co, NC have 75 acres on Stony run . . ." This data was given to me by Betty M via the Embler Family Genealogy Forum a few days ago.
I descend from William Imbler and Frances Sears and would be interested in comparing/exchanging data with you.
