Hi,
I Hope you don't mind me answering this ( Most of my husband's tree come from the Mumbles/Oystermouth area so I spend a lot a time researching that area) ,this maybe them ?:
Piece 1424/23 folio 009 schedule 051
Address Mumbles Village:
John Thomas, Occupation Mariner age 50 (c1791) from this county - yes
Ann Thomas age 50 (c1791) , from this county - yes
Thomas Thomas age 10 from this county - yesI also answered this back in sept 04 and posted the details , I don't know if you have seen it as my post is one but last in that thread, and you haven't replied to the two last posts in your old thread regarding your families you are researching, so you probably haven't seen them.
It's under your thread "name interests in Swansea" (also posted you a few links which may or may not be of any help to you in your old thread
The thread below:

"There is a John thomas in the 1841 census c1781 , occupation Mariner, oystermouth, Ann C1871 and Thomas c1831 ( which matches the son Thomas's age that you've given) in one household ( the other children could have left home by 1841) a lot of those lighthouse keepers were mariners before and after. No address sorry, it just says Mumbles village
There are not lot of people with the surname Thomas in Mumbles village in the 1841 census ( 26 people in total that I found with my search )
There is a Martha thomas who is a servant age 15 ( working at another house) c1826( which seems to match your Martha's age . There is only one Martha Thomas in Mumbles in 41. There is also William c 1816 and this william's , occupation is also mariner. He is living with a Mary Thomas , occupation housekeeper c1776 . It dosen't say the relationship in the household, so there is no way to tell if this is his mother or his Aunt )
Marianne , Walter and Jane Thomas I can't find those names in Mumbles in 41 ,the girls may be there somewhere under their new married name. The rest of the boys "David' may have moved out of Mumbles , or maybe out at sea on census night, or even died
Could be yours, may not be either. But the ages seem to be matching up. So it may give you something to check up on.
It may also be worth you doing a search in google with the persons name , and the word Oystermouth or Mumbles, it can bring up some results that may be relevant to the family you are looking for.
Hope that is of some help to you."I also posted you a few links in your old thread which may or may not be of some help to you
