Kassey, Welcome to WikiTree!
I'm not sure if this is the correct couple, as you didn't give any dates or places, but an Ada M Curtis married Frederick W. Fox at Brentford, Middlesex, England, during the 3rd Quarter, 1936.("England and Wales, Marriage Registration Index, 1837-2005," index, FamilySearch (https://familysearch.org/ark:/61903/1:1:QV8D-V72M : accessed 12 April 2015), Ada M Curtis and null, 1936; from “England & Wales Marriages, 1837-2005,” database, findmypast (http://www.findmypast.com : 2012); citing Marriage Registration, Brentford, Middlesex, England, General Register Office, Southport, England.).
Is this the correct couple? If so, we may be able to find more. If not, please give more informaiton, as, believe it or not, Fred Fox and Ada Curtis are not uncommon names.
