Jim, Mary Ann Schaar was the half sister to Charles Edger Schaar. Their father Daniel Schaar was married to Sarah Bliler and then to Mary Jane Eaton. There were 7 children with Sarah and 4 more with Mary Jane.
I have a little info on Mary Ann, but would like more. I am also stuck when it comes to Daniel Schaar and Mary Huber, all I know basically what you've stated in your post. Do you know any more on those two???
