I added some sources to Delbert and some notes. I was hoping to find reference to his birthplace, but only find he claimed to be natural born on his WWI draft registration.
However, just found they are on FamilyTree ID G4K4-XWJ where it is claimed he is the son of Lewis, and the name is a derivative of Trudeau.
It is funny he is not showing up in any other documentation... The link to the Malone newspaper does work for me, it opens a vie of 3 pages, on the right most page, on the next to the right most column is the little blurb.
Good hunting.
