From the vocabulary word for the flower (via Old French, from Latin lilium), regarded in Christian imagery as a symbol of purity. In recent times, it has become a popular component of compound names such as Lily-Anne, Lily-May, Lily-Rose, and Tigerlily.
Japanese: ‘blessed well’; found mostly in western Japan and the Ryūkyū Islands. There are several unrelated bearers of the name, the noble ones descending from Izumo no Ōmi, an ancient chief of present-day Shimane prefecture. Some others descend from the southern Fujiwara, and another group from a branch of the Minamoto.
