Hi David
I also have Gould's in my Tree - but not Thomas b.abt 1876.
I have found the marriage registration for Thomas Owen Gould to Beatrice Lewis in Bridgend Glamorgan in the Dec Quarter 1897 - Volume 11a Page 1214 - which fits in with them saying they have been married for 14 years on the 1911 Census. If you requested that certificate from the General Registry Office you would get the father of Thomas owen Gould and then you should be able to pick him up with some accuracy on the 1891 Census with his family.
Hope this helps.
Regards Norma
