Hi
This won't help with the marriage but I have found the family in 1871.
Forge Row, Christ Church, Rawmarsh
Thomas Day aged 36 boilermaker born Ulster
Elizabeth aged 32 born Kidderminster
Five children, the eldest being 13 but I can't read the place of birth, perhaps someone else might be able to help.
RG10-4708
Folio 16 Page 26
Regards
Kirstie
