Welsh form of Henry, from Old German heim and ric — ruler of the home. The Welsh spelling has climbed steadily since devolution in 1999.
Harri was given to 100 babies in England and Wales in 2025. Its best year was 2016, with 170 registrations. The name is absent from American records, so there is no US curve to compare it against.
