Ah ha...im trying all these sites, and they want damn money...and im not sure its the right information before i shell out for them....
Three things I have found that have sparked my mind....
I recall that my grandfather was called 'Dermot Francis Matthew McAuley' at his funeral, and those two middle initials keep appearing on sites...
Secondly, for the marriage to my nan...the surname 'Cooke or Bruce' is appearing, which Ive heard family members mention.
And thirdly, looks like they got married in Surrey? which is peculiar as my nan was always around the Acton (ealing district) area.
