Derry top 40 surnames – does yours make the list?
Thankfully local genealogist and historian Brian Mitchell has the answer having sorted the Dohertys from the McLaughlins, and the Gallaghers from the Kellys, in his book ‘The Top 300 Surnames of Derry-Londonderry’, published by Clearfield in Baltimore in the United States.
The book is based on the 1989 Foyle Community Directory, which lists 1,860 unique surnames in Derry City.
Brian looked at the number of entries and ranked the surnames in order of mentions. Where is yours in the list?
