Can anyone tell me anything of the family from which this lady may have come? She was married to James Pierson of Balmadies (Scotland). I have no dates for her or her husband, but her father-in-law, Robert Pierson (1701-1763), married in 1740. Her second son, also Robert, was a merchant in Riga and married Charlotte Hay, the daughter of John Hay, also of Riga. She herself is described in a Pierson genealogy as "of Livonia".
