Looking for McMann / McMahon in Palo Alto or Cerro Gordo Counties I know that at least one, Peter McMahon, stayed in the area. My GGGrandfather, Charles James McNally (b.1860) married Mary Ann McMahon (b.1848) November 25, 1877 in Mason City, Iowa. Mary Ann and Peter were sister and brother. I know of a few other McMahon's, but just started my McMahon search. CJ McNally is one of the sons of Myles and Mary McNally of Emmetsburg, Iowa, but he moved to Austin, Minnesota.
Thanks,
