I am sorry for the late reply to your message as I am just reading it now. My Regans are from "Drinagh West" which is close to the Sh. Isl.today but back then it was sooooo far away due to roads and transportation. The Regans are plentiful in South West Cork. Have you found that any of your Reagan's lived in Dunmanway? If you do let me know as I am familiar with the records of that area. There has been multitudes of records for Dunmanway area online over the last 10 years due to a few gracious genealogists that reseached, copied and posted all that they found of the area.
