Merribeth, of Old English origin, is an uncommon yet charming given name. It is composed of two elements: 'merrie', meaning 'happy' or 'joyful', and 'beth', a shortened form of Elizabeth, which means 'God is my oath'. Thus, Merribeth can be interpreted as 'happy promise' or 'joyful oath'. This name was particularly popular in the 19th century among English-speaking populations. It has since been used sporadically, adding to its unique and distinctive character.
The name Merribeth saw its peak popularity during the late 1940s to early 1950s with a total of 28 births recorded between 1947 and 1956. However, it appears that this name's appeal declined significantly afterwards, as only 25 more babies were given this name from 1960 to 1972.
