Eli’s many marriages are a bit hard to untangle. The 1910 census listed his marriage to Sarah Alice Pugh as his fourth, but I can only find three in the Morgan Co. marriage records.

His death certificate records Eli Ferguson, age 77 years 3 months 1 day, born 12 Dec 1868 in Morgan Co., Ky, died 13 Mar 1946 in Lykins, Magoffin Co., Ky, married, husband of Dora Ferguson, cause of death probably arteriosclerosis and heart failure, parents unknown, informant Mrs. Henry Keeton, Edna, Ky.

See the notes for his marriage to Emma Lumpkin for the 1900 census reading, and the notes for his marriage to Sarah Alice Pugh for the later census readings.

Morgan Co., Ky marriage records list the marriage on 5 Dec 1896 of David E. Ferguson and Emma F. Lumpkin, at Wiley Lumpkins by N. C. Adams, witnesses Thomas Nickell and Newton Carter.
