The only child here born after Lyman and Elizabeth married is the youngest daughter, so who are the rest?  The males in their 20s are too old to be Lyman's sons, but the rest could be his children from a prior marriage; however, I do not find our subject in an earlier census (the Lyman CORBIN in Ohio is not our subject).
