Many thanks Aghadowey - I have the birth and marriage certs. I also could not find any birth for a George Beck, or any other names born to the couple George Beck and Mary Bell.
I was trying to get a response from the original sender 'grindstonedave', as he would appear to be directly related to the family, and would probably want the info I have.
I have all the info for Georges siblings ( four) and his fathers siblings, and back to the original Beck settler in the Donegore area - John Beck, born c 1680's, to a John Beck of Downpatrick born c 1650's - died 1718.
