I have a William Dunn (born about 1820 Ireland)on an 1870 Fed. Census in Taunton,Bristol Co., Massachusetts. His wife is Margaret(Ryan)(also born Ireland about 1825) Children:Patrick 19, John 17, Michael 14, Mary 4. All children born Mass. Michael ended up in Cherokee County Iowa. We are trying to connect him to other Dunn's in the Cherokee area but believe we need to go back to Ireland to do it. I can't find anything beyond 1870 for this family. Does it connect to your's in any way? Long shot I know.
