To be more specific, the family in North English, Iowa and vicinity was that of Solomon Perrin (ca. 1784 - 1872).He had two sons who had families of their own:Thaddeus and Ephraim Porter Perrin.
Ephraim Porter Perrin (1834-1897) is on the 1880 census of Willow Springs, Howell County, Missouri.This is in south central Missouri.I have no idea why they would have gone there, or whether they stayed down that way.However, Ephraim's kin would have still been in southeastern Iowa, so I suppose that there's a chance that one of Ephraim's sons could have gone back to Iowa and become Burr's father.
As you can see by an 1880 census search on familysearch.com, Ephraim Porter Perrin and his wife had at least three sons:Stephen, William and Arthur.
You can find Thaddeus and his family on the 1880 in Lime Creek, Washington County, Iowa.Thaddeus Perrin's sons were Jonathan Robert Perrin (1872-1947), Levi Wesley (1875 - ___), William Henry (1878 - ____), Steven Delbert (1880-), and Charles Porter Perrin (1885-1918).
I realize that this is a long shot, but hope that it proves of some help to you.
