I'm searching for my Grandmother's ancestry. She was Katherine Luise Roettger. Her father was R Henry Roettger. I believe he is Reinhardt. Here I get stuck. I believe R Henry's father was Henry Roettger. I can only find census record in 1900 for this. However, at that time, Henry was married, for his second, to Carolina. The children living with them were: Clara, Henry, Louis?, Ida?, Anna, and Carolina.

Any information you might have would be greatly appreciated!
