I am also updating what I have found so far. My name is Brad Johnson and Elmer Chalupa was my Grandfather. I will send you an invitation to the family tree so you can see who is who and when. Looks like we are long lost relatives on the Chalupa-Johnson Side. My Grandmother was Fransic Chalupa and was previously married to Elwood Duncan which is my mom's maiden name.
We have a big tree to go over and look forward to getting information from you also.
Lillian Edgar was maiden name born abt 1892
