When were kids allowed to marry at age 12 in the US? You are just sayin'...
In Kansas, actually, common law marriages are legal when the girl is just 12...even now. Here's some more information:
"In addition to statutory law, Kansas is one of the few states in the union that recognizes Common Law Marriages. The age required for Common Law Marriage in Kansas is lower than that required for a statutory marriage by K.S.A.23-106, above. For Common Law Marriage, the female must only be 12 years old, the male 14."
since world war 2 I think only Kentucky. Before 1860 practically everywhere.
