I just started searching my ancestors on my mother's side. Theresa Aigner was my grandmother. She moved to Aurora when she married my grand father Matthew Roetzer. It was an arranged marriage and he came from Bavaria to Perry Ok. I lived in aurora until 1978 when I moved to Phoenix Az. I recognize all the aigner names that you mention. We lived at grandma's on Loucks st. until I went to Madonna High school. Isidor and Sebastian lived on Grand Blvd. They were grandma's brothers. I would love to be in touch with some of my relatives. my mother passed away 2 years ago. she didn't talk too much about the family. I do remember her talking about visiting her grandparents at the farm in Perry when she was a child. mom lived to be a very very healthy independent woman until 97 years old.Mom's name is Theresa Roetzer Walgren. I Bonnie Mcginn. I am 71 years young.
