You mentioned that John emigrated in 1633. I have some information that may clarify the dates you have. He was born to John Kaighin and Jane Connell (Cannel) on 25 Jul 1661 in K Michael. I have an article I received from the IOMFHS written by Elaine Cannon Nichols, titled "John Kaighin, Manxman, Who is John Kaighin of New Jersey, America." In it she suggests that he first emigrated to Ireland where "He may have found comfort among the Quakers". Having no money for passage, he became indentured for four years to Thomas Warne and arrived in the colony of East Jersey about Mar. 31 1683/4.

Hope this helps.
