I have the citizenship records of Stephen Conroy, born in Ireland, went to Camden East for many years married in 1876 to Margaret Haley. Left and went to Carthage, Champion NY in 1878 through the port of Cape Vincent.(as per papers)
The border crossings start after that on ancestry.com

Would people have taken a ferry from Kingston to Cape Vincent. Do they have records for these crossings? in 1878? or was that port so small it didn't matter?
I am just drawing a blank of where to look.
Are there any Lennox Addington, or Frontenac newspapers that go back to 1870's on a website (Napanee Beaver) the website paper of Record does not include these yet.
Any advice?
Karen
