May f
English: pet form of both MARGARET (SEE Margaret) and MARY (SEE Mary). The popularity of this name, which was at its height in the early 20th century, has been reinforced by the fact that it fits into the series of month names with APRIL (SEE April) and JUNE (SEE June), and also belongs to the group of flower names, being another word for the hawthorn, whose white flowers blossom in May. It has been out of fashion for a time.
