RE; George Kellow who married a woman named Margaret. My mother, Mary Agnes Kellowwas born 1895 in Oregon Township, Pa. to George and Margaret Kellow. Her birth certificate lists George and Margaret Kellow and her death certificate lists George Kellow and Margaret Hayes. The 1850 census for Honedale Pa.lists Moses & Bridget Kellow showing 9 children the youngestbeing George who was one year old in 1850.
Not sure if this is the same George Kellow but it is the closest I have found. I understand that Pa. is full of Kellows so maybe this needs to be researched a bit more.
