My maternal grandmother (Rose Louise) was a Kagen but very little is known about her parent or grandparents. She had a 1/2 sister, Berneice Kagen.
Her father was John W. Kagen (b. Abt 1874, d. 1939) and her mother was Jenni M. Martin (b.1886, d.1961).
We believe her great grandfather was a German immigrant b. Abt 1830 somewhere in Germany but that's where the information stops as there is confusion about his first name (Mar*S, Morris, Moritz).
Any tidbits of information and/or leads is greatly appreciated!
