Hi Aghadowey, thanks for your reply,
I don't know how but my sister has a marriage certificate from my grandfather Samuel Shields to his first wife my grandmother Jane Gardiner Forde, that was 23rd April 1935 and they still lived in the same road Abercorn drive Ballyclare,
It does state on the certificate his fathers name but no mothers name,it does say deceased for Robert Wallace and the certificate was dated 23rd April 1935. But I can't seem to find any deaths of a Robert Wallace after 1914 when Samuel shields was born upto 1934.
