I had a great-aunt who's name was Pearl Sahl. She lived in Boone IA. She is some how related to the Klinger,Klinkafus, or Summers part of my family. My grandparents were Robert Opal Russman. Am trying to put together a family tree for my kids so they can have a scense of history. any help would be appreciated. Thank you in advance. Shari(johnson)Knapp
