Hi, I will go ahead and post this in response to your message, even though it was posted.
I am Jonathan Aigner. My father is Stephen, the son of Garret (G.H.) Aigner. He is currently in the hospital in Bryan with several ailments. He is 90 and is the only surviving child of Gustav Adolf Aigner. The last one to pass away was Laura a few years ago.
Otto was the nickname of the oldest son in the family. In fact, this might be a mistake and Otto might have been his real name. I'm not sure.
They're an interesting family. That's for sure.
