I don't have much info on the Waage branch, but I do know where they owned land in Madison county. I've also been to the Mundis cemetery where they are buried. They have a modern monument. There is an old marble stone for four of their children who died at young ages. I would like to repair that stone in the future, but it's a bit of a drive for me from Oklahoma. ( I have a monument restoration business.)
I have photographs of Maria Doebele Waage's sister, Marianna. Do you have any old photos of the family? I assume Johannes and verena Doebele are buried in the Mundis cemetery, but there are no stones for them. Suppose it is possible for them to be buried at marine or highland, but I do not know.
I look forward to corresponding with you in the future. You can email me at idswart(at)hotmail.com.
