Following that theory there is a John Thomas Nunn and Ethel Sanderson on the same page for a marriage in 1907 Dewsbury.
Could be barking up the wrong tree but you never know.
They do pair up as bride and groom. She was 23 a weaver father George deceased coachman if that matches at all.
Actually think it does. Same church and I think same residence Nelson St? for Ethel and your bride.
