in the early 13th century the monks of sele priory (st peter's church, upper beeding) began a mission to the area of st leonard's forest near horsham, and established a small mission base, naming it lower beeding. despite being some away, lower beeding remained a part of (upper) beeding parish until victorian times. the existence of lower beeding led to differentiation in the name of the original beeding in some medieval sources, adding the 'upper'.
