I assume you have something on him as you know who he married.
I am also assuming ??? that you want to know about his early life ??
This looks like him in 1900, first census after he was born.
1900 ATLAS, PIKE, IL
Elisha, age 33, day labourer, born July 1866 IL parents born IL, married 5 years
Mary J., age 23, wife, born Oct. 1876,IL parents born MO, married 5 years, 2 children born 1 living
Harry L., age 3,son, born Aug. 1896 IL parents born IL
Earnest, age 14, brother-in-law, born March 1886 IL parents born MO
so looks like he was brother to Mary J. Since Mary J. was born about 1876 she should be in 1880 census with their parents
First though I found her death which shown her as wife of Elisha Johnson and her parents as John J. Browning and Sarah Kerr

so - either parents birth place wrong in this census or in 1900 census but that is not unusual
Do you have the census from 1910 on or do you need them for Ernest ? I see he is in census up to last one for 1940 so he was alive at that time.
I can give you more on some of his siblings to as I see Fred and Homer are in census - haven't checked for the rest yet - waiting to see what you need.
