Phyllis Thede was born in 1954 to an African-American family in
Chicago, Illinois. Her family moved there from the Deep South in the
Great Migration of the early 20th century. Her family later moved to
Creston, Iowa, in the southern part of the state, where her father worked on the
Burlington Northern Santa Fe (BNSF) railroad, which had established a major division center here, with machine shops and roundhouse. Phyllis attended local schools and started her higher education at
Southwestern Community College. There she met Dave Thede, whom she married in 1974. His family was German-American, with ancestors who immigrated to the US from the 1840s. They moved together to
Le Mars, Iowa where they both attended
Westmar College. ==Work and family==
