Hi Bearfoot
I have researched my Croshaw family, whilst I don't remember them, (I am a bit younger

)and I was not born in England, however I have an Aunt who may remember something. I think we are probably related.
I have a bit of information on this branch of the Croshaw's, not a lot more than you have, but here goes.
George and Elizabeth Ruth Burrows had four children according to the 1911 census
Agnes May b c1902 d c1991
Ethel Daisy b c1903 d c1984
Edwin Harry b c1907 d c1978
Amy Rose b 1911
Ethel did marry Geoffrey Croshaw who was her cousin in 1939, this was his second marriage. Geoffrey was my Grandfather's brother. Geoffrey was married to Fanny Gregson - 1917 and they had three children
Arthur b c1918
Violet b c1920
Sheila b c1929
I have found a marriage for Arthur to a G B Slater, so far I haven't found any offspring.
I hope some of this may be useful and look forward to your comments.
