Naomi, I have recently found the name EIDAM in my ancestry. I have a copy of a very old picture of Mr. & Mrs. EIDAM and daughter. They were parents of Katerina "Catherine" Eidam Frisch, b. 1837 in Germany and lived her adult life in Glenvil Nebraska. She was my g-g-grandmother. I know Catherine had a sister, Margaret Eidam Seibel that lived in Pittsburgh, PA. Would love to hear from you if this sounds like your line.
