I'm glad that you asked about Jacob's death. I didn't have that information until now. I decided to look again to see what I could find. I found a Jacob William Day that died on June 4, 1942 in Carroll Co., Ohio. There wasn't any other information on this record. The record was on Ancestry.com. I also checked at
http://pilot.familysearch.org and didn't find this record. This is the same county that Ursula died in 1944. Her death record [an image] can be found at the pilot.familysearch site.
I have that Nela Ursula Kisamore married Jason Dice Harper, who was the son of Philip Henry Harper and Rebecca Ruhoma (Harman) Harper. I do research on all descendants of Isaac Harman, the 1st.
