I have an ancestor named Modelene Kimmenhour, 1847-1925. Born in France, married David Woolf (1842-1921). Arrived in the US 1853. Lived in Stewartsville, Warren County in the 1870s then moved to Holland Township, Hunterdon after that, which borders Pattenburg. I do not have any information as far as her parents or siblings. I wouldn’t be surprised if she was a direct descendent of your ancestors. Perhaps daughter or sister of your Joseph Kimenhour. I have seen her last name spelled a few different ways.
