Re: Surname - prottey
There don't seem to be any Prottys iin Kellys in Birmingham at the beginning of the 20th century (none up to 1921), but in 1940 the following (2 spellings) occurr:
Commercial
Nellie Prottey (Mrs) Newsagent, 20-21 Arsenal st small heath
Albert Protty. Ladies hairdresser.32 Kings road Hay Mills
Thomas Protty. Fried fish dealer, 63 Grange hill, small heath
Private
William George Protty, 65 Steyning Rd, south yardley
After this they seem to be, not exactly common, but present.
