John King and Sarah Otto were married by Rev Hugh Urquhart, St John's Church, Cornwall(page 81) no witnesses listed. Now that does not mean that was where they were married but that was the Rev.'s church. They use to ride on horseback to surrounding areas and marry people as ministers were very scarce back then. I found they even got married by Rev's out of their religion. But still a good start :0)
Also listed a daughter was born to a John and Sarah King named Barbary. She was baptized by Rev P German Sept 4 1859-no church or area listed.
