Lem's parents were James J. YB (1810-1889) and Leah Jane Elam (1813-1885).
His wife was Caroline Read (1844-1880).
Lem died on 9 March 1880 in Paradise, Wise County, Texas and his wife Caroline joined him in death on the 30th of March 1880.
Since I can't locate death certificates for either one, I'm left guessing why they died within 21 days of one another.
Indian raids had ceased in Wise County before 1880, and I haven't found mention of any outbreaks or epidemics occurring that year. Perhaps it was influenza.
I'd appreciate hearing from anyone who knows their cause of death.
