Tonnie was most popular in 1960, when 51 American babies were given the name — ranking #2,537 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 1,157 people named Tonnie.
Across the whole record Tonnie is a unisex name — 59.1% of the 1,157 Americans given it were girls and 40.9% were boys. It changed hands: since 1968 it has gone mainly to girls, having gone mainly to boys before that.
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.
