No problems D,

After all someone has to keep the forum's top people on their toes ;-)

The above Marriage gains a little more detail from the GlosBMD site, don't know if you use it at all ?

Marriage Details

Groom Surname Groom Forename Bride Surname Bride Forename District Parish Building Year Register Entry
ROPER Philip Clem DALE Winifred Edith Gloucester Gloucester St Mark 1938 31 No 8 175

This site doesnt have the above Birth or any others tho ?.
However it "suggests" that Philip is a traditional ROPER family name in the Gloster/Cheltenham area before and since.

Think this is your Philip from FreeBMD:
