Cathlyn

Cathlyn is a feminine name that serves as a variant spelling of Kathleen or Cathleen, ultimately derived from the Greek name Catherine meaning "pure." This particular spelling combines the more traditional "Cath-" beginning with the streamlined "-lyn" ending, creating a balance between classic and contemporary. While never among the most popular variations, Cathlyn emerged primarily in the mid-20th century when parents began exploring alternative spellings of traditional names. The name carries the same dignified history as its more common relatives while offering a slightly distinctive presentation. Cathlyn peaked in usage during the 1950s and 1960s but has since become increasingly uncommon, giving it a vintage quality that sets it apart without seeming overly unusual.

Pronounced KATH-lin.

As of October 2026, Cathlyn ranked #8525 in US births in 2024 SSA, peaked at #2526 in 1953.
