I have a picture that could possibly be Louisa Rosenow. My grandmother is the great-granddaughter of Martin John Juhnke and Louisa Rosenow. I was digging through grandma's old pictures one day, and ran across one that I believe is Louisa. I also have pictures of Martin and Louisa's daughter, Caroline Juhnke Schoenian, and her children. Are you interested in any of these pictures?
