[Transcribed information mainly from the early 1820s]
"BOYNTON, a parish in the wapentake of Dickering; 2 miles W. of Bridlington. The church is dedicated to St Andrew (see Churches for photograph), and the living is a discharged vicarage, of which Sir William Strickland, Bart. is the patron. Population. 123." (There is further information for Boynton).
"CAYTHORPE, (High and Low) in the parishes of Boynton and Rudston, and wapentake of Dickering; 1¾ miles E.N.E. of Rudston, 3½ miles W. of Bridlington. Population 26."
For those interested in the Boynton family name, it seems that the Boyntons left Boynton around 1231. There are however Boynton family graves etc. in Barmston, Burton Agnes and other parishes (see the East Riding Parish index for links to all the parishes).
There are several web sites dealing with the Boynton family, including one set up by Bob Boynton.
