From the experts:
Kay, a cigarette-smoking, nightclubbing name of the 1930's, could be ready for a comeback along with cousins May/Mae and Ray/Rae.
Kay has been out of sight since the mid-eighties, but was in the double digits from 1936 to 1945, attached to several glamorous actresses of the period, such as fashion plate Kay Francis, as well as Eloise author Kay Thompson.
Kay was also once a unisex name, as in Sir Kay, in Arthurian legend one of the Knights of the Round Table.
Bottom line: Parents in search of a fresh, more cosmopolitan alternative to Kate might consider Kay..
