My Grandfather and Uncle (Paul and Dick Douglas) used to farm ground right about where you are talking about.They called it the Weeks place. It was kind of the headwaters of Sring Canyon. Do you have the section, township and range of the place you are talking about? The Herdrick family farms ground around there as well.

The Names Feil and Lang look to me like they are Germans from Russia. I have distant Feil cousins and I think some Lang ones as well.
