Hi
Taking into account the marriage found in 1891 this could very well be the 1891 census for the couple. I have had a look through for a James and Ada Spencer and this is the only pair. Of course somehow it would need verifying.
1891 census
address 5 Union Street
Elizabeth Spencer, head, widow, age 50 born Lancs Manchester
Jas Spencer, son, married, age 23, framer born Yorkshire Cleckheaton
Ada Spencer,daughter in law, age 23,card filler up, born Yorkshire Cleckheaton
Eliza Jane Spencer, daughter, age 19,factory operation, born Yorkshire Ceckheaton
Sam Spencer, son, age 16, factory operation, born Yorkshire Cleckheaton
John Richard Spencer, son, age 14,

? (cant read) boy, born Yorkshire Cleckheaton
Civil parish: Cleckheaton

County: Yorkshire
Source information: RG12/3610
Registration district: Bradford
Sub registration district: Cleckheaton
ED, institution, or vessel: 21

It seems very likely this is the correct family, with James having a brother Sam and then naming his son that.
I will have a look and see what else I can find.
