I have a Mary McKee, daughter of John and Elizabeth MCKEE. Mary "Polly" married G.B. ALEXANDER May 25, 1835 in Des Moines. I found an article written about Des Moines (Burlinton) and it said that Mary MCKEE ALEXANDER had a brother and a sister living up the bottoms, and something about their cabin being where the Sister's Hospital is now. I wonder if they are related.
