Thank you for looking for FTC WELLS.
Since posting the request in 2011 I have found a birth entry on Rootsweb free BMD for Frederick Theodore Claude WELLS in 1893 in Tunbridge Registration District, Kent.
On the 1911 census Florence TUCKER is single and living with her sister's family in Norwood, London. I have still not found a marriage for Florence Amelia TUCKER and FTC WELLS but have at least narrowed it down to between 1911 and 1926.
FTC WELLS was buried in Banff in 1975.
Thank you again for your help.
Janet
