I am wracking my brains to think why John's brother in law would put down Anglesey as the birth place of his wife and John, if he did not believe that to be correct. In which case, why did John subsequently claim to have been born in Liverpool.

Anglesey is not vastly populated even now, and in those days would have been less so; that family in 1841 is more than likely to be the same as the one in Merthyr in 1861. ALSO......John's children's names may be another pointer:

His siblings in 1841:
Mary
Catherine
Elinor
William
Ann
Elizabeth

His children include:
Catherine
Eleanor
Elizabeth
William
Ann
