The early HYLANDS in Ringmer live in the section of the parish adjoining Laughton, and they oscillate between the two parishes. East Hoathly is immediately the other side of Laughton. Young people seem to have moved pretty freely between parishes, but of course were sent "home" as soon as they fell ill or got into any trouble, or if their families began to grow.
"Home" was of course usually the last parish in which you served a complete year before you married, so you might not actually think of it in that way.
My working assumption is that John HYLANDS was a son of George HYLANDS the younger, who mainly lived in Laughton. He figures in "Diary of a Georgian Shopkeeper" published most fully by OUP and written by the East Hoathly village shopkeeper of the 1750s/1760s, Thomas Turner.
