I wrote about 8 David Irlands a couple of years ago and got poor response. My emigrating David Irland came from Wigtown in Wigtownshire in 1773 with his wife Leonora Murray and children. He settled in Northumberland County PA. He was interniewed by customs when he was leaving for PA. They confimed that he was a successful smith in the town of Wigtown. All Irlands I know are from him. They went on to NY and Michigan.I believe there was an Irland in NJ in the 1770's named John who might be another family. Likewise I found an Irland in Louisiana that is probably unrelated. What do you know of your Irlands?
