hi, The DeLeske family name is a hard one to find information on the net but here goes.
My grandfather was Jacob DeLeske, he had many children:Trudy,Henri-william, Jake, Helen, Erma, George and Nellie. My father was Henri-william. He died in 1968. I know that Erma was married to John Odermatt, Trudy married a Jack Sharpe, Helen married a Norman Clark. Most of them have children. The name DeLeske can also be written differently: deleske, delesky,etc.
My grandfather came from russia, moved to British Columbia, and his children from there moved on...vancouver, winnipeg, california, etc. If you have any info, please let me know.
Take care.
