Got All Those Sibling Obituaries

I’m trying to track the movements of a relative who lived in both Chicago and upstate New York between 1900 and his death in about 1935.

Fortunately he had over a dozen siblings who survived to adulthood, many of whom he survived. The next step in my research is to track down obituaries for these siblings and see where it says he is living–assuming he is listed as a survivor.
