I do not have much info on Thomas but I do on John. He would have been my great-great-great-great grandfather. The info I have says he was from Westmoreland born Februaury 14 1805. He married Margaret Wilson in 1826. I'm not sure the year they immigrated, I know it was before 1842. That is the year they moved from Luzerne County Pa to Pike Township, Bradford County Pa. My father and brother still run the dairy farm today in the same spot that they settled. John with other Alderson's are buried in a cemetary in Pike Township not far from our farm. There is a Thomas Alderson there,he was the son of John and Margaret. His date of death was Jan. 14 1833,5yrs. 3mo. 12 days.
