Kay

The name Kay is found both as a surname and as a given name. In English-speaking countries, it is usually a feminine name, often a short form of Katherine or one of its variants; but it is also used as a first name in its own right, and also as a masculine name (for example in India, the Netherlands, and Sweden). The alternative spelling Kaye is encountered as a surname, but also occasionally as a given name, such as actress Kaye Ballard. Provided by Wikipedia
