Hi Seviad, this probably won't help you but my g g gm Mary Rees is shown on the 1841 Cenus living at Tyreynon, Llandebie/ Llandybie with the family of Richard & Rachel Hughes.
Later on that year, on 24 Dec, Mary married Rees Davies in the Llandebie Parish Church.
If you've anything on Mary and/or Rees then I'd love to hear about it.
Regards, Rob Davies
