Kirke was at least a second year during the 1995-1996 school year, and became a Beater on the Quidditch team after Fred and George were banned (OP21). Unfortunately he wasn’t very good – the most memorable moment of his season was when he fell backwards off his broom in fright during a match against Hufflepuff (OP26).
Andrew is the English form of the Greek name Ανδρεας (Andreas), which is derived from ανδρειος (andreios), meaning "manly, masculine" (Behind the Name).
Kirke means "church" and derives from Old Norse Kirkja . As a surname, it is found mainly in Scotland and the North of England (Internet Surname Database).
It may be that the name Andrew Kirke comes from combining the names of the magician (Andrew Ketterley) and his nephew (Digory Kirke) from The Magician's Nephew by C. S. Lewis.
