I'm looking for information on Joseph Furguson/Ferguson born abt. 1820 (possibly in Illinois). Joseph was married Mary Myers Lindsay on 2 Sep 1847. Mary was sister to my gr. gr. grandfather Thomas Myers Lindsay. I found Thomas living with Joseph and Mary Furguson in Fayette, Lafayette, WI, on the 1850 census (3 children listed). Mary disappears from the records after that. I found a Joseph Ferguson married to Bridget on the 1860 census in Wiota, Lafayette, WI (7 children listed). His birthdate and place match the Joseph on the 1850 census.
Joseph and Bridget (maiden name possibly Perkinston) may have moved to Iowa by 1868. There's a family in Corwin Twp., Ida, Iowa that seems to match on the 1870 census. I'm trying to find out if these three families are in fact the same family and hopefully when Mary Lindsay died and who her children were. Any help sorting this out would be greatly appreciated.
