Isaiah and Rebecca had three children: Sarah C., Emma Elizabeth, and George.
Rebecca is the daughter of Henry Ackman and Judy Turner. Most people forget about this Henry and put your Rebecca and her sisters in other Ackman groups.This Henry died in 1838; his wife had died previous to that, I assume since she wasn't named in the will.Henry's three daughters were Sally (md. Thompson Sanders), Rebecca (md. Isaiah Green), and Nancy (md. Samuel Harmon).
Guessing by ages, Henry Ackman who md. Judy Turner must be a brother to William Ackman (md. Elizabeth Wynn), Charles Ackman (md. Sally Johnson), Elizabeth Ackman Pavey, and possibly an old John Ackman.
Emma Elizabeth md. Wm. D. Ackman, son of Isaac and Nancy M. Harmon Ackman of Schuyler County, Illinois.(The Schuyler County branch is my line. Isaac was the son of William and Elizabeth Wynn Ackman.Nancy Harmon was a sister to Samuel Harmon named above and they are children of David and Elizabeth Youngman Harman/Harmon.)
George md. Addie Riggs.I have her listed as daughter of Matthew and Elizabeth Ackman Riggs.Elizabeth was the daughter of James and Polly Badders Ackman. (James was the son of William and Elizabeth Wynn Ackman.)
