I just found your entry that is over 3 years old. Nonetheless, I think your Great Grandfather is my Great Uncle Frank. The 2 brothers that you mention that go to N.Dak. are my Grandfather, Thomas V. and his brother Henry. But this Henry and Thomas are the sons of the Henry that came to the US in 1881. The older Henry (my Great Grandfather) was known as "Wee Harry, the fiddler" and he immigrated with his wife, Hannah Murray Devlin and sons Francis, James, and Thomas. The Henry that goes with Thomas to N. Dak.was born in Illinois.
