Mererid

Mererid is a Welsh feminine name derived from the Latin word margarita, meaning pearl, which itself traces back to Greek margarítēs. It represents the native Welsh adaptation of the broader European name tradition that produced Margaret and its many cognates. The name has been used in Wales since the medieval period and remains distinctly Welsh in character. Related forms include Margred, the more common Welsh equivalent, as well as Margaret and Margarita in other European languages.
