It can be difficult, Hilary. I started off with no Jones in my family until I got back to great grandparents and then they just grew!
I will have a look at the Ruabon records produced by Clwyd FHS as the records showing on FindMyPast/FS are not always accurate/reliable. Also, given that Street Is(s)a was in the Rhos area, they might well be non-conformist.
It might take a while.
Do you have the census refs for William and Elizabeth? Note that the 1841 census is missing for the Ruabon area.

Hi Gadget, thank you as always for your help!
Here's the 1851 reference:
Town Morton Above
County/Island Denbighshire
Country Wales
Registration district Wrexham
Sub-registration district Ruabon
ED, institution, or vessel 2m
Piece 2503
Folio 281
Page number 2
Household schedule number 6
And the 1871:
Civil parish Moreton
Ecclesiastical parish Rhos
Town Rhos
County/Island Denbighshire
Country Wales
Registration district Wrexham
Sub-registration district Ruabon
ED, institution, or vessel 12
Household schedule number 14
Piece 5653
Folio 4
Page number 3
And looks like I actually do have them in 1881:
Civil parish Ruabon
County/Island Denbighshire
Country Wales
Street Address Pant
Condition as to marriage Married
Occupation Coal Miner
Registration district Wrexham
Sub registration district Ruabon
ED, institution, or vessel 12
Piece 5513
Folio 47
Page number 5
I guess I have not found them in 1861, and as you said, 1841 is missing...
