I'm also interested in a MASSEY-CROSSE family in Bristol (England) but am getting nowhere fast with them.
My particular interest is Yvonne who was born in 1905, married in 1929 and died in 1959. I believe she may have been a sibling to Cecilia Gertrude (b 1908) and Samuel Victor (b 1911). Samuel married in Derbyshire (England) in 1941 and there is a son (still living) born to the marriage.
I've also found a Clement who was born in "North London" and, at the time he joined the Territorial Force in 1909, he was living in Whiteladies Road, Bristol (England). He was a dental student working for Mr MASSEY-CROSSE. He left the force in 1910 to emigrate to South Africa. More than that I don't know but there seems to be a very good chance he was the son of Victor MASSEY-CROSSE (b 1856, London).
Any help sorting out Yvonne's family would be much appreciated. I believe Victor may have been her grandfather especially as she had a son Victor.
