Hello Dave and thanks for your kind offer.
Florence's marriage was registered in Shaftesbury, Dorset (I've also posted on the Dorset board).
Arthur's marriage was registered in Mere, Wiltshire:
Arthur Ernest GATEHOUSE Q2 1911 (5a.461) and an entry the same quarter for Katherine Mabel READ (5a.462a) ... a good candidate for Arthur's wife.
If you have access to the registers, could you confirm Arthur's father for me please. I'm hoping it's Frederick GATEHOUSE, blacksmith. Any other information (occupation/residence/witnesses etc) would be gratefully received.
With kind regards,
Joy
