Eira is a Welsh name that simply means "snow"; it is also the name of a Norse goddess of healing, Eir, in a Scandinavian form. Soft and short, it fits in with Isla and Freya and appeals to parents who like nature names without the obvious ones. Eira is just becoming known in the United States: it rose from around number 4300 in 2015 to number 1749 among girls' names in 2025, its highest rank so far.
