I have just checked the 1881 census and it shows:
William SNELL M Male 47 Caerleon, Monmouth, England Pesway Railway Inspector
Ann SNELL Wife M Female 46 Eglwysilan, Glamorgan, Wales
John SNELL Son U Male 21 Llanfabon, Glamorgan, Wales Railway Station Master
Henry SNELL Son U Male 19 Llanfabon, Glamorgan, Wales Railway Plate Layer
Thomas SNELL Son Male 14 Llanfabon, Glamorgan, Wales Scholar
Mary SNELL Daur Female 11 Gelygaer, Glamorgan, Wales Scholar
David C. SNELL Son Male 5 Gellygaer, Glamorgan, Wales Scholar
Mary F. BOWEN Serv U Female 18 Llantrisant, Glamorgan, Wales General Serv ,
but I am now intrigued because the Bible entries do not show a Thomas (c 1867) at all! It has got:
John b.15th July 1859
Henry b.16th April 1861
Margret Ann b.13th Aug 1865 d.1st Nov 1863
Lewis b. 1st Oct 1864
James b.21st Jan 1869
A Mary b. 27th Nov 1869
Sarah b. 9th Feb 1872 d. 9th April 1873
William b. 12th Sept 1874 d. 5th Oct 1874
David Charles b. 27th Nov 1875
so I wonder what happened to Lewis and where did Thomas come from - possible he was Lewis Thomas I suppose, but William's entry does not show a 2nd name.
