The Podington parish register transcript has marriage on 17 May 1772 of James Sarjeant of Podington, bachelor to Mary Wilkins of Podington, spinster, and also the baptism on 5 Dec 1746 of Mary Wilkins, daughter of Richard & Alice Wilkins.
I have a note saying that his brother John Serjeant of Wymington, bachelor married Rebecca Wilkins of Podington, spinster at Podington on 25 Nov 1770
Regards John
