Andrew Simpson was born in Nottingham, NH. On June 29, 1800, he married Sarah (1781?-1854), the daughter of Robert Lapish. Simpson worked for a time as a shipbuilder but also made money by investing in merchandising.
The couple lived near the Durham end of the Piscataqua Bridge and also in Durham village in a house that later became the parsonage. They had three children: Andrew Lapish (1800-1895), Caroline (b. 1802), and James (b. 1804).
