I have not found a marriage reg - could you post further details of where you found the information or what other information you have?
I wondered if "T" Stubbs could really be "F" Stubbs?
There is a Frank Stubbs with wife Mary Ann (she was b Gibraltar)
Frank was a Chauffeur but by the time his daughter Daisy married he was a driver in the armed forces Royal Garrison Artillery
It looks like this Mary A's surname was Poolton - witnesses at her marriage to Frank were Francis & Rose Poolton
What was your \grandfather's name?
