History & Origin

Kelsei is a modern respelling of Kelsey. The older name comes from Lincolnshire places such as North and South Kelsey, usually explained from an Old English personal name (often given as Cenel) plus eg, 'island, dry ground in marshland.' The surname travelled into first-name use and became a popular American girls' name in the later twentieth century, and lighter spellings like Kelsei followed it (said 'KEL-see').

It appears only in very small numbers against the commoner Kelsey. Rare, bright, and surname-flavoured.

Did you know? Kelsey began as an English village name on low marshy ground - the second part, eg, meant an island or a patch of dry land - long before it became a bright unisex first name.
