I add my thank you, Ed, for this most helpful post. Can you tell us how many years, typically, there were between the person's arrival date and the date of the naturalization papers? This would help those who have firm or approximate dates of arrival know in which year's records they should search. The answer will most likely be "it varies" but you have to start somewhere. My great-grandparents arrived, I think, about 1875 (Timothy Murphy of Reentrisk). James P. Murphy Stuart, Fla.
