I am currently doing research on my Williams family whom with David Williams and Catherine Richards were residing around Llanfair, Mathafarn Eithaf, Anglesey, Wales in the 1851 census. David and his children Owen and Emma arrived on the 'Lord Stanley' in Jan, 1852 to Victoria. Owen David Williams was christened in January, 1831 Wales and married Hanora Reid/Reed (daughter of John Reid and Ann Higgs) in 1863 Ballarat, Vic. He died in September 1907 and buried in Ballarat, Vic. I do have some more information on the family, I believe David and Catherine had more children, but not sure.
If any of this rings a bell please reply or email me at firstname.lastname@example.org
