1870 US Federal Census
Washington Parish, Louisiana
Jerald, William, age 22, male, white, farmer
Jerald, Liza, age 25, female, white, keeping house
Jerald, Ophelia, age 1, female, white

The ditto marks indicate the last name "Jerald" as William and Liza apparently lived next door to his parents, and were listed on the same page of the census records. They are listed as a separate household, so apparently they didn't actually live together.
