Christening of John Croucher in the IGI on 9 November 1718 at Saint Thomas, Portsmouth, Hampshire, parents Thomas Croucher and Jane on the same day as Anne so I assume they were twins.
I cannot find an entry for his marriage, and there is only one daughter christened in Portsmouth, mother's name Mary.
