The Nathaniel H. mentioned in prior message was born in Mich. in 1850. I've not yet linked him to parents. From message board postings, he apparently moved to Illinois.
Another finding is the presence of Cone family members in SE Michigan. Earliest noted in Hillsdale is Devoclet (1845) later recorded as Devoclut, with spouse Fanny in 1850, and a Michael & Maria in 1860. Also, Washtenaw County, east of Hillsdale, has a Cone Road.
From Nat'l. Archives; An October 1866 petition for pension for minor children of Sarah Harget (nee Hungerford) had James Hungerford and William W. Purchase as testifiers to the contained facts.
