 Francis Duncombe's Katonah: The History of a New York Village states that ""the John Jay School, opened Oct. 1, 1956, in Cross River, is the only high school"" [in the Katonah-Lewisboro District]. Moreover, she explains that the district was created in 1952 by the consolidation of Lewisboro District No. 1 with Katonah's District No. 10. John Jay H.S. was built in Cross River, which is part of the town of Lewisboro, and wouldn't even have been part of the same district as Katonah when Exley attended high school. The Katonah school (sometimes called the Huntville Road School) was K-12 until the building of John Jay, and since then has only been an elementary school. Yardley was misinformed, but this may be the source of the confusion: the yearbook was called ""the John Jay"" (see: http://www.classmates.com/yearbooks/Katonah-High-School/107075) even though the high school was not. No surprise there, as John Jay's yearbook was ""the Statesman.""   "
