One thing I noticed which may relate to the mystery of the marriage dates...Bessie's year of birth is wrong on her profile. She was born in 1894 instead of 1892. So, she was only 16 in 1911, the year of both the Illionois and Indiana marriages. Perhaps, she and Mr. Lang eloped for the first marriage. Perhaps, her parents objected and had the marriage annulled. Perhaps, they relented a couple of months later (because Bessie was pregnant with her and Samuel's daughter who was born in November 1911) and allowed Bessie and Samuel to marry again. Lots of speculation on my part, of course.
