Greatings from Alexander Corners, Henderson, New York ! I am the self proclaimed mayor of Alexander Corners, home of the Robert Alexander Family and later Jonathan , Reuben, Joseph and Aaron. From what I have seen, I agree, Joseph was a son of Jonathan S. Alexander. What are the points or items of dispute? Hello to Jonathans relatives that I havent spoken with for a while. I have been working on William Henderson bio and also Capt. Samuel Rhodes and Capt. William Rhodes.
