There's a marriage of a William Rigby of NuL, occpn brewer, at Stoke on Trent (St Peter ad Vincula) to Elizabeth Powel, of Stoke on Trent on 28 Jul 1814. Had been casting around for a possible William John/John William Rigby marriage.
They may have had a daughter Anna Maria, 16 Jun 1815, NuL, - this time occpn. is labourer.
Alerted to your latest post. So marriage/baptism from FindMyPast and newspaper details from BNA.
