I'm looking for half-brothers and sisters of my gr grandfather, Joseph Irwin Pogue. Joseph was born to the second wife of Robert Gordon, Nancy Irwin. Robert Gordon's first wife was Sarah Brown, by whom he had eight children, I believe. I have a photo of a house in Paw Paw, Illinois that indicates it was home to Robert. I've noticed that some of the family spells it "Poage", and others, "Pogue". Robert lived from 1798 - 1876. Joseph lived from 1848 - 1940.
