I am part of the Rochester/Breckinridge/Myers families of Nathaniel Rochester of Rochester NY.I do have access to Nathaniel Rochester's family records.Although my connection is in Danville KY at Center College where the Brackinridge/Myers of Rev William Breckinridge family intermixes with the Rochester Family of Nathaniel Rochester.
Rev William Breckinridge DD was Vice President John Cabel Breckinridge's nephew and John Cabel Breckinridge was President James Buchanan's Vice President. He also lived in Frederick Md and Nathaniel Rochester lived in Hagerstown MD
Then James' brother was married to Pittsburgh Song Writer Stephen Fostor's sister.Stephen Foster was a close friend of Susan B Anthoney and Elizabeth Cady Stanton.
The Stanton families connected Hagerstown and Frederick MD to Chicago Ill
