Maryann Jarman married William Ricketts. William was born on 19 Sep 1748. They had the following children:
Elizabeth Ricketts married Thomas Melton. Fanny Ricketts married Bennet Williams. Mary Ricketts married Daniel Ballieu. William Ricketts married Susan.
Shame on me for not writing down the source for this information. I don't know that the list of children is complete. I assume the birth date is from William Ricketts's Revolutionary War pension application.
