I may have information about Alexander and Jane Corrough McKee that you already have but wanted to post this to you. My father and I just returned from Stuart, Iowa where both Alexander and Jane are buried. My records indicate that Alexander was born 13 Jan 1811 in Belfast, Ireland and married Jane Corrough abt 1834 in Belfast. They evidently immigrated to the United States in 1855 and moved to Muscatine county, Iowa and then on to Stuart. The Stuart library has a nice picture of one of Alexander and Jane's children, William and his family. My records indicate that Alexander and Jane had the following children: Hugh, Thomas, Samuel, Robert (my great grandfather), Alexander, Agnes and Eliza.
If you have any information that you can share I would appreciate it. I currently am waiting on marriage records from Belfast where I think that Alexander and Jane were married.
