I am a great-great grandson of Elizabeth Koepfgen. She married Daniel S. Oliver in approximately 1858 in Port Huron, MI and later lived in Wales Township, St. Clair County in 1860, then in Au Sable, MI in 1870. She later married William Chute. She is buried in the Mt. Pleasant Cemetery in Wales Twp., near the grave of William Koepfgen.
I am trying to find any information regarding the Koepfgen family (i.e. where they lived while in Canada) as it may lead me to information regarding Daniel S. Oliver who I cannot locate prior to the 1860 census, nor after the 1870 census. Anything you may be able to provide is appreciated.
