According to the 1920 Census of Louisville, KY, Earl Edsell was age 20, and living in Louisville, Jefferson County, KY with his wife, Margaret age 23. At the time, they had two children: Joseph - male age 2, and Thomas - male age1.
At The time, there was also a boarder living with them. I'm not sure the I believe the first name reads, "Charles," and the census indicates that his last name was also Edsell, but has him specifically listed as "boarder." This could be Earl Edsell's brother Charles.
