Is Kay short for anything?
Not always. Kay spent long stretches as a name in its own right, so a longer form is not guaranteed to be hiding behind it. Still, old records do use it for Katherine. Less often it stands in for Catherine and Karen. Expect it in American and British records, mostly 1900s. Let the surrounding documents settle which one your ancestor carried.
