.Is there anyone out there who has traced his durgin ancestors back to the Civil war and found that Cornelius mustered in as Cornelius Duggan and out as Cornelius Durgin? This man was baptized as Cornelius Duggan in Bandon, Kilbrogan Ireland. That's the man I'm researching. All family members since the Civil war have used the name Durgin. I'd like to hear from you.
