Pearl
Maghan is a rare spelling variant of Megan, which is a Welsh diminutive of Margaret. The name ultimately derives from the Greek word 'margarites', referring to a pearl. While the 'Meghan' and 'Megan' spellings were highly popular in the late 20th century, this specific 'Maghan' variation remains very uncommon.
