Marykathryn was most popular in 1994, when 20 American babies were given the name — ranking #7,853 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 507 people named Marykathryn.
Across the whole record Marykathryn is a girl’s name — 100.0% of the 507 Americans given it were girls and 0.0% were boys. In births since 2016 it is 100% girls and 0% 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.
