Magarethus / Margareta / Margaretha / Marguerite / Margherita

Magarethus is a rare variant of the name Margaret, which derives from the Greek word 'margarites' meaning 'pearl'. The name gained popularity in medieval Europe due to Saint Margaret of Antioch, a virgin martyr of the 3rd or 4th century. Its usage spread widely across various cultures and languages, leading to numerous forms and spellings.

While Margaret is overwhelmingly female, the 'Magarethus' spelling, particularly with the '-us' ending, suggests a Latinized form that could historically have been applied to males, though it remains exceptionally rare. The '-us' ending is characteristic of masculine Latin names, indicating a potential, albeit uncommon, historical male usage or a very archaic/formal female usage.
