Marybeth is a compound name derived from Mary and Beth, combining the meanings of both names. Mary is often associated with "drop of the sea, " "bitter, " or "beloved, " while Beth means "oath" or "God is my oath. " The name Marybeth reflects a classic combination popular in mid-20th-century America, aiming to move away from the overly common name Mary without straying too far. Despite its peak popularity in the mid-1960s, when about 400 babies were named Marybeth annually, its usage has significantly declined, with fewer than 20 babies bearing the name each year currently.
