I am trying to trace the parents of the above William. I have his date of birth from his Masters Certificate of Service No. 44.327 dated 21st January 1851. This is 15th August 1818. On the 1861 census return he is shown as having been born in Ynyscynhaearn, Caernarvonshire.
He was married to Elizabeth Anne Evans (1822-1914) and she remarried a Robert Jones (1804-aft 1881) sometime before 1871, when they are living together as husband and wife.
Can anyone help?
