I am hoping to make a connection with a descendant of one of these three brothers. All were born in New York. Archibald was an officer in the Marine Corps and fought in the Mexican War. He died in San Francisco, California in 1873. His brother Charles came to California after the Mexican War and was president of the San Francisco Committee of Vigilence during the 1850's. He was a real estate broker. David also came to California after the Mexican War from New York. I don't know what he did. Any help in making a contact will be appreciated. David
