IGI has a Jane Iremonger m 16/1/1613 to Nic Perkins at Stanbridge, Bedfordshire. I would think that she is daughter of John Iremonger (died 14 April 1613, residence "of Stanbridge Beds") but this is only because he moved to Stanbridge in the 1600's. John's son John died at Stanbridge 7 Jan 1637. He had a daughter and several grandchildren all christened at Stanbridge. Have you found out any more since you posted your message?
