His death certificate records Lafe Day, age 76, born 13 Jan 1868 in Morgan Co., Ky, died 30 May 1943 in West Liberty, Morgan Co., Ky, occupation farmer, married, husband of Clair Day, age 72, father John Day, mother’s maiden name Lizzie Caskey, both born in Morgan Co., Ky, cause of death cerebral hemorrhage, informant Clara Day, West Liberty, Ky, burial in Lenox, Ky.

Since he was listed in the censuses as 3 in 1870, 13 in 1880, and 43 in 1910, he may have really been born in 1867. The 1900 census said Jan 1868, though.

Holt is apparently the same as the son listed as Ollie in 1900 and 1910. If the ages are correct, William must be the same as Ernest B.
