HI! I am researcing the brother of your Elise -- Alden Willever Kelly. As you already know, their parents were Dora (Isadore/Isadora - found spelled both ways) Willever and her husband, Wesley Harrison Kelly (thanks for telling me the middle name - I only had his middle initial).
They married April 11, 1882 in McLean Co, IL (where Bloomington is located) and then moved shortly after (or right away) to Clinton, Clintonia Township, DeWitt Co, IL. where Wesley already had a job.
I found a newpaper clipping dated Feb 9, 1883 announcing that Isadore's mother Mrs. Willever of Bloomington was in Clinton visiting her daughter Mrs. Wesley Kelly. The two counties border one another and Bloomington is straight up from Clinton.
Alden was born in Clinton, and attended school in Clinton as late as 1903 (have group school picture of him and his class). They evidently moved sometime between that 1903 picture and 1910 where they show up in the census living in Portland, Oregon. The 1920 and 1930 census have them in Jennings Lodge, Oregon.
I also have info on the Kelly line if you're interested. I'm more than happy to share anything I have. Benita
