Kathrin is a female name.
Kathrin is a German short form of the name Katharina and probably derived from the Greek name Aikaterine, but as well from the Greek goddess Hecate.
Kathrin means “each of the two” (from “εκάτερος/hekateros”), “pure” (from “καθαρός/katharos”), “torture” (from “αἰκία/aikia”), “one hundred” (from “ἑκατόν”) or “far away” (from “ἑκάς”).
