To anyone following this post: I can report that my cousin located and had copied the Immigration Card of one of the subjects of this search; Michael O'Neil.
Data on the card gives his address as Montague-Lewis Co N.Y. the file reference as;File D 1458, and the Title and location of the court as Lewis Co. Supreme. Country of birth Ireland, age as 55. Date and port of arrival in U.S. as Feb. 1853 Morristown N.Y. and Date of naturalization as June 12-1860. Listed names and addresses of witnesses/sponsors F.G. Newton-Pinckney N.Y. and Martin Murphy, also of Pinckney, New York.
Unfortunately, this card does not give the date of birth as a statistic, only the age of the subject. Hoped-for information that this card also fails to provide is town or county of birth...only Country is listed.
This is, however a great piece of his/our history to now have in our possession.
