Gladys sent me a load of emails today with images of various records pertaining to George Daniels, Levi Daniel, and their families. I will post them this weekend.
Meanwhile I was looking through some of the notes I brought home from my grandmas and came across one titled "Clay Co Register of Deaths"
Report No 543 date of report Aug 2, 1880
He was farmer born in England. Died July 5, 1880. Resided IL 30 Years?
Died at Oskaloosa Ill of Rheumatic Fever
Buried July 6, 1880 Oskaloosa (Saswell Undertaker)
I'm not exactly sure where the information came from but I did not previously have a citation for his death date.
Update: I posted this last night and this morning I get an email from Gladys containing images of the actual record! There are two pages, scroll within the scribd window.
