Hi Kim
Pleased we have the same Sarah. According to my research she was the dau of James Scott c1748 (illegit son of Jane c1728) and Sarah Welsh c 1747. Her parents William Welch c 1718 and Mary Hepplewhite c1718. Mary was dau of George Heplewhite c1677 and Sarah Rootlish c1683. It seems they had 10 children, the youngest of whom may well have been the famous George, cabinetmaker. George c1677 was the son of Cuthbert Hepplewhite c1647 and Jane Reed c1650. In turn Cuthbert's father was John Hebblewhaite c1620 and his father George c1585.
I hope this is of interest. Best wishes, Jon.
