Capt Reuben F Kolb and most members of his battery lived in Barbour County AL. A S Kennedy also lived in Barbour County along with several other Kennedy men. Since they had been born in North Carolina, there may be a connection. In 1850 many of the same Kennedys were already in Barbour County, while Albert can then be found in Duplin County NC. There must be a number of family connections in these two counties.
There are minor mistakes in this otherwise well-written article about Capt Kolb --
