Recorded 1914–1998 · United States
Kathyleen was most popular in 1951, when 26 American babies were given the name — ranking #3,200 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 541 people named Kathyleen.
Across the whole record Kathyleen is a girl’s name — 100.0% of the 541 Americans given it were girls and 0.0% were boys.
Counted from every US birth the Social Security Administration recorded under this name, so it reflects use rather than opinion. A name given to fewer than five babies of one sex in a year is withheld at source and is not counted.
