Hello, I am trying to trace back the McAllister part of my family. My great grandmother on my father's side was Katherine McAllister. Her father was Thomas McAllister bMar.1819 in Ohio, His father was Walter S. McAllister b about 1790? and I believe his wife's name was Catherine Whan. I can't seem to locate any information on them though. Walter and Catherine had several children - Mary, Thomas,Nancy, Sarah, John, Elizabeth, Margaret, Andrew and Robert. If anyone has information on this line I would appreciate any help. Thank You
