can't depend on census records
1910 census ancestor was divorced, 1920- she was a widow/
did not remarry raising 2 children living with her parents.
women in general were looked down upon as easy when they were divorced.
I think that is why on one census they are divorced and another they are widow
or they were never divorced in the first place. Think it is called "separation of bed and board"?, usually it is filed in a court if a women wanted to keep her money and not be responsible for his debts and x was a no good cheat.
