I could see Graves living in Bassingham in the 1890's, 1900's but not 1911 - so apologies if I missed them.
But as I could not see a family in 1911 called Graves, and no birth for a Margaret Graves in Bassingham, I wanted to know if they were there as farmers for only a short time, which could still be decades.
Also, because of the lack of suitable births for Margaret's son, then either incorrect spelling, or birth out of district, but we were told birth at Bassingham.
So as the poster has been in contact with people in Bassingham, I wondered if they had identified wartime farms and tenants etc.
