I'm looking for any information anyone has on the following people. Please note that their birth/death years are my best estimate based on what little documentation I could find.

Horace J. Grant: 1839-1913
Horace Grant: 1804-1874
(Unknown) Grant: 1745-?

The elder Horace Grant is believed to have been born in Pennsylvania around 1804 and died in New Jersey around 1874, so the unknown Grant should have been residing there at least at that point in time. I'm specifically looking for info on the unknown person, since this is my direct family line, although anything on any of them would be appreciated.
