History & Origin

Kathyjo is a spoken-together double name from the middle of the twentieth century, uniting Kathy with Jo. Kathy descends from Katherine, a Greek name long understood as 'pure,' while Jo shortens Josephine or Joan. Rather than a hyphen, families often wrote such pairs as one word on the birth record, capturing the everyday habit of calling a girl by both names at once.

The name was never widespread, given to only about twenty girls a year at its brief peak around nineteen-seventy. A Kathyjo from that moment is in her fifties now, her name a small time capsule of mid-century naming.

Did you know? Smushed double names like Bettyjo and Kathyjo were a real fashion in mid-century America, especially where a two-name calling name was the family habit.
