History & Origin
Kathline is a variant of Kathleen, the beloved Irish form of Katherine that traces back through Caitlin to the Greek word for pure. The trimmed spelling shows up in early and mid-century records, when Kathleen itself was riding high among Irish American families.
This spelling crested in the early nineteen-fifties and faded over the following decades. Given to only about twenty girls a year, a Kathline from that peak is now in her seventies.
