Thanks avm228, having looked at some old info I collected I think Carol may have indeed found the right Frank Connor above.
On the marriage certificate his address is 345a Northolt Road. Profession is mechanical engineer. The witnesses are Michael and kitty shannon, Mary's (Frank's wife, my grandmother) brother and sister.
As mentioned above I had some info someone on WDYTYA kindly provided and there is a Francis Connor in Harrow with the Baldwin family in 1939.
1939- 87 Sherwood Road , Harrow U.D., Middlesex, England
Francis Connor, 30 Sep 1913, Male, Engineers Turner, Single, 263, 6

Do you think this is him? Looks pretty good to me? It's his name, South Harrow, correct year of birth and the Lancashire connection.....
Thanks again. Nick
