That’s the Leeds one though, isn’t it, not the Salford/Manchester one. 
Are you thinking they could be the same person?
There's a surprising number of Fenton / Finton Moores about
One in Edinburgh, Scotland in 1851
Denis Moore Head 36 b abt 1815 b Ireland
Ridget (sic) Wife 33 1818 b Ireland (probably meant to be Bridget)
Mary Ann Moore Daughter 11 1840 b Ireland
Rose Moore Daughter 5 1846 b Kirkcudbright, Kirkcudbrightshire, Scotland
Catharine Moore Daughter 3 b abt1848 b Scotland
Anthony Moore Brother Married 20 1831 b Ireland
Fenton Moore Nephew Unmarried 20 1831 b Ireland
From ages this Fenton would be son of Denis and Anthony's older brother.
The Leeds Fenton has a mother born in Air (sic) Scotland. Maybe this is the same one.
