Looking for any information on my family. The best information I have is that my ggg grandfather James Wemys McCallan (Macallan) was born in Scotland in 1817. He came to the US sometime in the later 1840's and fought in the Mexican American War. He also went to Calf for the gold rush and eventually settled in Doniphan county KS after marrying Anna Hack of Prussia Germany. I am seeking any tips or help at all. thank you.
