I don't know how accurate this info is, I got it from other Woolfolk researchers. Justine Woolfolk was born before 21 Jul 1706. She was the daughter of R. Woolfolk and E. Boswell. Her siblings were Robert, born before 10 March 1688, died 1744; Elizabeth "Betty", born c 1690; Richard, born c 1694, died 1767; Joseph, born 1696, died 1770; Mary, born c 1699, died after 1722; and Martha, born 28 Mar 1703. All of these children got married and had children of their own.
