I know it has been a while since your post but I hope this can help.
My tree shows Charles True Adams (1900-1942) was the son of Samuel Adams b. 1871 and M. Louise Koerner b.1872 of St Clair Co. Illinois .Samuel was the son of Charles Adams an Attorney in Chicago b.1843 in MA and Emma S. ? b. 1844 in NY.
Charles and Emma appear in the 1870 Census but by 1880 Emma is listed as head of household living with her son Samuel and daughter Julia b.17 Jan 1874.
I also note that Charles True Adams had children named Samuel and Julia.
