In the summer of 1920 Peter Mueller and George Levin, in their twenties, came from Kentucky to Wimbledon to work in the harvest fields. Levin returned to Kentucky once the harvest was finished. Peter Mueller remained to work for Harry Green. In the spring of 1901 he began working for Nick Flagler and in 1903 began farming for himself, with his brother Jake assisting.
On February 10, 1904 he married Margaret Levin, sister to George Levin, in Kentucky and they came to farm the plains of Dakota, a decided change for his bride.
