Fred Barlow was my grandfather. From my understanding Maggie was born in Iowa, not Ireland but none of my family can be 100% on that. Her father was James and he appears to have been born in Illinois. Everything that I can find suggests that at some point he and his wife moved to the Dakotas.
As far as George Barlow there really isn't much information that I can find on him because my father and his siblings were to young to remember him.
