I to have Kaighen's in my family tree, John Kaighen (M) Ann Quirk, daughter Mary (m) 16 Sep. 1828 Kirk Michael, Thomas Carran Jr. Mary had a son Thomas Kaighen (b) 24 Nov. 1820 Kirk German, before her marriage to Thomas. I may have a little more Kaighen information, but my family history on the IOM is the Carran/Karran family.
