I came across the marriage banns in the parish of Hackney St John, London of William Peters, a widower, and Elizabeth Elger Cautley called on 13 June 1824 and 20 June 1824. On the second calling, this note was added:
‘Forbidden this 20th June by me, John Elger, on authority of the Father of the said Elizabeth Elger Cautley’ It was signed by John Elger.

Whatever family argument arose, it would seem that William and Elizabeth got their own way, because on 9 August 1824 the couple were married at Greenwich St Alfege church.

I noticed that neither of the witnesses bore her surname.
