The last name has been spelled many ways, Pelum, Pullium, Pulliam, and Pullum, so searching census records has been fun. 'Olive' has a granddaughter named, Mary Olive, so I'm thinking that 'Olive' may have also been a Mary Olive and thus the census having one name one time and the other in the next census as I have no other Mary as siblings for her...Olive was my g-grandmother.
Right now I'm tracking down whether Olive was an Indian or an older generation was my Indian. I have a photo of "Grandma Breese", and she is in what appears to be Osage Indian dress; now I'm trying to determine which generation this photo falls into as I was not aware of any Indians in the family line.
good luck finding more on your Andrew, if I dig up anything on him, I'll let you know.
