I'm looking for this line:

Isaac Julian b. abt. 1817 Ohio, married to
Elizabeth Stevenson abt 1817 - 1859
11 children: Wesley R (see below), Rebecca, George, John, Mary, Sarah, Miller, George, Joe, Andrew & Ida.

Wesley R Julian b. 16 Oct 1838 in Berlin, Illinois, d. 16 Sep 1907, married to
Nancy Vickery b. 16 Dec 1842 in Ohio d. 08 Dec 1909
Both died in Jefferson, Adair, Iowa.
6 known children: Mary, Anna Florence, Emily, Melissa, Isac Frank, and Albert.

Anna Florence Julian marries to a David Porter on May 3rd, 1882.

This family appears on the 1880 census for Dover, Bureau, Illinois but eventually moves on to Jefferon, Iowa. Anyone tracking this family?
