I asked Mom about Anna Durandetti last night. She remembers her well and could probably tell you whether your picture is of her. If there are other names associated with your family or Anna, let me know and I will talk with Mom and get back to you.
Walter Mollar was my Grandmother's brother. He was born in 1905 so the age in your photo would be about right. He lived most of his life in the Clearfield County PA area. My PA relatives lived in Curwensville. Mom told me last night that a cousin from Curwensville is also doing some genaology work.
By the way, you mentioned that the photo you have was from your great aunt's wedding...what are the names of the happy couple. Mom may recognized them.
Have a great vacation!
