Wife is Helena S. Unknown b. 1836 d. 1879, no marriage record found.
There is no other Ida Larson b. ca. 1860-1863 residing in Henry County.There are a number of public family trees who all give Ida's year of birth as 1863 as shown in 1900.Additionally, her parents could not read/write so it is unlikely that they knew the exact ages of their children when they reported such to the censustakers.It is that or Ida chose to make herself appear younger.
A couple of trees list other individuals as the parents of Andrew but it is unlikely that Jonas and Ann Larson are not the parents of the Andrew, rather they are most likely to be his parents.From 1860 on through 1900 the Larsons resided in Henry County, and though I could not find a marriage record online for Andrew and Helena/Helen, it may be possible to find one with a search of the Henry County records.A search of church records in Henry County (specifically those churches located in Lynn, Illinois may produce a christening record which should be more accurate as to Ida's true year of birth as well as you may stumble upon a marriage record for her parents.
