The rest of the church dates from the early 14th century, when the church was extended to the current size and dedicated to St. Michael's and All Angels' Church. St. Helen's Chapel was incorporated into the north east section of the church and served as both a private chapel and burial site for the de Appleby family. Most of the tombs have been removed but the alabaster effigies of Sir Edmund de Appleby and his wife Joan, dating from 1375, still survive. The chapel would eventually become known as the de Appleby Chapel although it is currently used as the church vestry.
