I am reseaching the HEARNE family from Pontypridd, Glamorgan, South Wales but cannot find any of the family on the census for 1891, 1901, 1911 Thomas Hearne ( spelled HERN on his marriage cert) wife is Ann. They married 1881 born and married Pontypridd child William John born 1897 (Spelled HERNE on his birth cert) born and married Pontypridd The spelling changes to HEARNE with William John's son also named William.   I have tried all the spelling variations including HURN, URN, HEARNE, HERN, HERNE, and any other variants I can think of.   This family never left South Wales   Any suggestions on finding them on the census would be appreciated, thanks so much!
