I have no connection to any of those folks -- just trying to help.
1910 census -- Winnebago Co., IL -- Rockford
William O. Balsbaugh, 35, marr 2, m 1 yr, b. IL
Evaline K. Balsbaugh, 31, marr 2, m 1 yr, b. IL, 3 children - 2 living
Leroy Betts, 14, b. IL
Ethel Betts, 7, b. IL
IL Archives (on line) -- marriage index:
Eva Murphy m. William Henry Betts, 7/31/1899, Stephenson Co.
William Balsbaugh m. Sarah Hiteman, 4/22/1896, Ogle Co. (William's 1st marr)
Leroy was evidently from W. H. Betts' previous marriage. Couldn't find Eva & W. H. Betts in 1900 census.
Leroy burial info on www.findagrave.com
along with links to 2 wives and son.
Do you know when W. H. Betts was born or when he died?
