1830 - Mary and Morris Carothers in Indiana

In the 1830 US Census, in Indiana, Jackson County, Salt Creek, there is listed the following:

Mary Coruthers as Head of Household
1 male under 5
2 males of 5 and under 10
1 female of 30 and under 40

Mary is likely the widow of William Carothers, he having died in 1826.
The three boys are likely the sons of William and Mary, William, Isaac, and James.

Morris Cruthers as Head of Household
2 males under 5
1 male of 20 and under 30
1 female of 10 and under 15
1 female of 30 and under 40

At this time, Morris Carothers was about 22 years old.
The question is now, which of the females is Anna, the first wife of Morris? Either one makes for an interesting story. Is it possible Morris married Hanna when she was so young, and the older female is possibly a mother in law? Or is it possible that Morris married a woman at least 8 years his senior who had a 10 year old daughter? It's also possible the ages are a bit off. Hopefully, further research will shine some light on the situation.
The two boys are likely the sons of Morris and Anna, William and Joseph.

It is interesting to note that Morris married Diadema Ann Connelly on May 14, 1831, the year following this census. Diadema had been previously married to a man whose surname is Mitchell.

In the entry directly following that of Mary Carothers is that of Joseph Hanna. Is he related to Anna, whose maiden name was Hanna? Considering Joseph is between 50 and 60, he may be Anna's father.
