I don't know if its the same unit but a GOOGLE search game me the following hit about the contents of a time capsule:
Rochester Union Grays
The Rochester Union Grays were organized on November 19, 1838 as an independent military company. Although they did not enter any military conflict as a unit, they became a noteworthy social organization in Rochester, sponsoring balls and social events.
This program was printed in connection with their thirty-third Anniversary Supper held at the Osburn House on Saturday, November, 19, 1870.
