And here is a link for the book "A Place of Honour" for the geographical places in Manitoba named after Fallen Manitoba soldiers: VBy the way ... you should be entitled to receive, or at least buy if no one else in the family has received the first certificate, a certified and signed map honouring Stewart and showing the location of the lake. It comes with a letter explaining the honour and signed by "up there" officials and arrives in a tube. Its coloured and beautiful for framing

If you contact them and request one you'll find out whether you get a complimentary one or will have to buy one (very little money to buy them though!)

I have a copy (complimentary of WarAmps) of the Manitoba names and info extracted of just the RWR soldiers - below is exactly what's written for Stewart. I regret there is no photo of him included that I could scan and post for you
CULLETON, Lance Corporal Stewart R., of Badger (H 1713) Royal Winnipeg Rifles. He died on 8 June 1944 at the age of 24 and is commemorated at Beny-Sur-Mer Canadian War Cemetery, France. He was the son of Richard and Blanche Culleton and was survived by his wife Jean Culleton. Lance Corporal Culleton was "executed" while a prisoner of war after the Normandy landing.
Culleton Lake (64 N/14) North of Nueltin Lake was named after him in 1972.
That's it
