      Based on y-DNA results, we have discovered that Elias Kaighn (9153) is not in fact genetically related to the rest of the Kaighin family.  After some exhaustive research, we have discovered that Elias was not born a Kaighn, but more likely was born with the surname Cain or a phonetic equivalent.  Due to his proximity to other actual Kaighns in Gloucester County, New Jersey and also likely due to his own illiteracy, we theorize that record keepers began spelling it as Kaighn and by the time literacy stuck in his children's generation, the spelling was settled.  Other researchers have in the past attributed Elias parents as John Kaighn and Sarah McMullen, but this is not the case.  So most members of the NJ Kaighn Branch are not genetically Kaighns, they are most likely Irish Cains.  We have also found that there are three male lines of decent alive today who claim Elias Kaighn as an ancestor.  We have Y-DNA tested three of these lines and have discovered that there are three separate and unique Y-DNA haplotypes (signatures), so two of these lines comes from another source and are therefore not actually descended from Elias.  These are represented above as orange, purple and green.  Since descendants of Elias' sons William and James match each other, we can conclude that Elias' y-DNA haplotype matches that of Ray, David, William and Jim.
