"Second" - "Third"?!!
Does this woman think JAs just now got off the boat? I personally know some "fifth" generation JAs, and just recently held in my arms a "sixth" generation JA!
There are possibly much older JAs in terms of generations. The Shogun of Japan thought highly of Napoleon and sent him 24 of his best samurai, along with their entourage. Napoleon sent them on to America. These men were well trained in the art of fighting from boats. Although history seems to have lost track of them, the War of 1812 has a famous battle or two on Lake Erie, a body of water with a great deal of similarity with the Inland Sea in Japan. The Perry family went on to fame in opening up Japan to the world.
I have met JAs who had GGrandparents who knew the Perry family. They didn't count generations in those days.
Ms. Hahn is an idiot.
