CASTLE family in Somerset

[stevefoote]

I am trying to fill in some missing gaps in the history of my CASTLE ancestors.

Thomas CASTLE of Pembrokeshire married Esther ADDERLEY of Staffordshire in 1832.

Their eldest children were born in Staffordshire, and by the time of the 1851 Census they were settled back in Pembrokeshire. However, their eldest son, John CASTLE, aged 13 in 1851 Census has his birthplace listed as Somerset.

Has anyone come across his baptism around 1838 - or know of an 1841 Census index for Somerset ? I've tried freeBMD and familyrelatives.org for his birth without success.

Thanks in advance

Stephen Foote
