Hello I can answer most question about the Cornelius Gordon b. 1781of Londonderry Ire who Married Sarah Owen in !1805. Cornelius, my grandfather 5 generations above me - I know not of his parents or sibllings. The family stayed in Luzerne county PA. area or close NY until the civil war era. Three fought as Yankees. Thereafter many came to Oregon or Calif. I am working on the late generations, th decendents of Cornelius"s post civil war. Karen Gordon Portland, Oregon
