Mae is an alternate spelling of May, which was originally a diminutive form of Margaret, Mabel and Mary. It is most often used on its own now, often as a nod to the month of May. In the mid 20th century it became more popular as a middle name, or as the second part of a compound name, like Maggie Mae, Ellie Mae, Sally Mae etc.
