Signor Hanks, 38 years old, male, farmer ("), $1,500 in real property, born in Kentucky
Elizabeth (Hanks), 29 years old, female, born in Kentucky, person over 20 years old who cannot read or write.
Elijah (Hanks), 13 years old, male, born in Kentucky
Susan J. (Hanks), 11 years old, female, born in Indiana
Sarah F. (Hanks), 9 years old, female, born in Indiana
Matilda (Hanks), 7 or 8 (?) years old, female, born in Indiana
From this record, it appears that the family moved from Kentucky to Indiana between 1837 and 1839, which would be the birth years of Elijah (born in Kentucky) and Susan F. (born in Indiana.)
My wife's great-grandfather John William Hanks would not be born until 1856, which is the reason that he was not listed in this census.
I was researching this information because my sister-in-law had questions about Susan J. Hanks.
