hi kerry, I'm not a member of http://www.scotlandspeople.gov.uk/ so I cannot view records, but I can confirm that they have a record for Janet B Melrose born in Scotland (not Edinburgh) in 1913. Maybe somebody else with membership may be able to help you or you might consider joining yourself as you appear to have Scottish ancestry.
I'm sorry that I can't help you with more Melrose information but the info below may be useful...
Janet's marriage to Thomas in Q1, 1940 is visible in the UK BMD (
http://www.freebmd.org.uk/cgi/search.pl) and it appears that Thomas was married at least once previously (possibly twice). See records below (you can order certificates from the GRO (online or mail) using the Reg. District, Volume and Page references.

Thomas' birth in Cuckfield, Sussex is apparent in 1908 (another Thomas H Pateman was born in Pancras, London in 1901 so the third marriage in London is likely him and not "your" Thomas)...
