Have been following through on the Eileen b.1922 coming from Canada. Have worked out the Gurr family she came from but can find no connection to William Henry James Wigmore Gurr.
Lots of notes too copious to list all here right now - the end result being she was the dau. of Stuart/Stewart (varies from record to record) Gurr who married Florence N. Hills Dec.qtr.1918 Cosford, Suffolk. They both went to Canada in 1919 he a couple of months earlier. I'm guessing that Stuart/Florence separated/divorced when she came back with the children in 1930. It looks like she stayed here but son Rodney S. obviously went back because a border crossing 1938 shows him as a student of Edmonton, Alberta visiting a friend in New Jersey - his nearest relative shown as Stuart Gurr. Found Eileen - last address Wissington Fox, Nayland - going to Canada 1939 although age given as 19 when she was only 17 but clearly back here by 1940.
Her mother - Florence Nellie Gurr b.1/6/1799 d. Jun.1995 Colchester.
Stuart Gurr was the son of a Charles Gurr bc.1850 Shoreditch, son of a Henry, and Elizabeth Edwards bc.1853 Stowmarket, Suffolk - he was born 16/7/1893 (not 1892 as Canadian records show) in South Hackney - he and his mother went to Canada in 1907 and Stuart served with the Canadian Forces in WW1 and presumably how he met Florence. However, following back on Charles Gurr I can find no connection between him and WHJWG.
Whilst I feel that Eileen Hazel Gurr is the Eileen from Canada (no births in Ireland, Scotland, England or Wales) could it maybe be just one of life's coincidences that Walter Ralph's wifes maiden name was Gurr? One could go round and round in circles here - it seems to me your only option is to get the marriage certificate of Walter and Eileen to establish her fathers name. If it is Stuart then it would seem the 'Gurr' connection is indeed just a coincidence but if it is another name that will at least enable you to try and find said person who will hopefully link to WHJWG.
A real conundrum!
