This Mary Ann Hickman is often attributed to being a wife of a William Rice, father of JOnathan B Rice (1790 -1872 d Kankakee)
That is incorrect.
Jonathan B Rice's paternal lineage puts him in Group 14 of the Rice surname Y DNA project, very closely related with a John Rice, founder of Rice's Landing PA. There is no sourcing to connect him to Mary Ann Hickman
