Washington Irving, author of “The Legend of Sleepy Hollow,” followed the Rev. Dr. William Creighton here from Zion Episcopal Church in Dobbs Ferry. Irving was a vestryman, warden, Sunday School teacher, and regular parishioner at Christ Church until his death in 1859. The ivy on the church walls is from cuttings taken at Irving’s home, Sunnyside, and his pew is still marked in the front of the sanctuary.
