A William Conn was listed as residing in Tuolumne Co. in the 1920 census. He was born ca. 1840. Does anyone know anything about this man or could they find death certificate or cemetery information about him for me? Any help would be appreciated.

I found this early death record:

William Conn, age 81, died 9/12/1921 in Tuolumne County, CA.

You can always try for an obituary, if there was one from the county library.
