Hi Sue,
Thanks for your reply.
I am actually trying to find out who lived in a particular house in The Crofts in 1911 rather than the other way around! The house in 1901 was named as Ridgemont and occupied by Blanch C Cullin (?) aged 42 b. Castletown (and her domestic servant Christina Holt aged 19). I was unable to find her either as Cullin or Crellin in 1911. I believe that originally she lived at Westhill before Ridgemont was built, but this is the only information I have. My interest lies in the actual house occupants.
