Meighan is Welsh in Origin.

Meighan is a modern respelling of Meghan/Megan, the Welsh hypocoristic of Margaret. Margaret stems from Greek Margarites, ultimately from Persian marvarid, meaning “pearl,” so Meighan carries the jewel’s connotations of purity and value. Common variants include Megan, Meghan, Meagan, Meaghan, Meghann, and Maegan; diminutives such as Meg and Maggie are also used. Though the spelling suggests complexity, the usual pronunciation aligns with Megan: MEG-ən.

Usage of Meighan appears chiefly in North America and the UK from the late 20th century, part of a broader trend toward individualized spellings of popular names. The base form Megan has medieval roots in Wales, but widespread Anglophone popularity surged in the 1970s–1990s, with Meighan emerging as a distinctive alternative. Note that Meighan is also an Irish surname variant (from Ó Miadhacháin, “honorable”), an etymologically separate line sometimes encountered as a family-name-as-given-name.
