I started off with a George Roy Kitchen b 17 Jun 1891- born in Wentworth, Ontario, Canada.
I cannot find a death for him.
He might have married Elizabeth (Bessie) Butler Birkett 1885-1973 23 Jun 1909 York, ON, died as remarried Elizabeth Butler Knox, husband Howard L Knox of Lynden.
George Roy/H Kitchen born 9 May 1910 -1947 Zion Hill Ancaster, Hamilton Municipality, Ontario
Neva Margaret Esther 1912-1957/8 Putnam, Ohio.
James Sterling Kitchen 18 Oct 1913 Wentworth died 1996 married Jean Wells 1917-2015 Mindemoya, Cobalt, Woodstock, Port Credit.
Another alternative is this, as it has him with the same birth date.
There is a WW1 draft in the USA (Detroit, Wayne, Michigan) for someone called Roy George Kitchener with exact same birthday 17/6/1891.
Has a wife and three children. Lives at 238 Fullerton Detroit Michigan.
I would be most grateful if someone could please find him.
