Marykate is of Irish origin, derived from 'Máiríad', which means 'of the sea' or 'rebellious'. It's a blend of Mary and Kate, both classic names with rich histories. This name gained popularity in the late 20th century, often associated with the Olsen twins who were named Mary-Kate and Ashley.
The name Marykate experienced significant fluctuations in popularity over the past six decades, with a notable peak occurring around 1993 when there were 83 births, the highest recorded figure during this period. This trend continued through the mid-90s with high birth numbers but started declining steadily from the late 90s onwards, reaching an all-time low of 15 births in 2020. Despite the recent decline, there has been a slight resurgence since 2021 with 26 and 26 births recorded respectively for those years. Overall, Marykate has had a total of 2113 births between 1958 and 2023.
