Thank you so much for replying and for the valuable information you sent.
After I wrote to this forum on Apr. 26th, I continued my search for W/O1 D.G.Plyley and found some information on the Elgin County Genealogy OGS site.It took hours of searching but I finally came up with a couple of snippets of information that I thought at the time related to the information you sent.....and it was indeed the right Plyley family!D. G. Plyley was the son of Arlington W. Plyley shown on the 1911 census information you provided.I have written the Elgin Co. OGS and have also learned that the death I found there for a D.G. Plyley who died in 1969 is indeed the right man.
Thank you for all your help.It is much appreciated.
