If you are interested, and you have a male Horgan relative willing to participate, the Hor(ri)gan DNA project might be willing to sponsor your family's participation with a y37 marker test. *Unequivocal*knowledge of your townland, village or town of origin and a willingness to share your family history data are requirements for sponsorship. It sounds like you know with certainty your lineage is from Killorglin.
The project funded two Hor(ri)gan participants in 2015.
We have eight Hor(ri)gan members who share some genetic genealogical relationship to each other.
There is also a member with Castleisland, Kerry ancestry who doesn't match the group of eight members.
If any of this interests you, email Susan firstname.lastname@example.org
for more information. I will be presenting this project at the Cork Genealogical Society in May 2016.
