Did Edith Edwards marry a Perry Dedrick? I found the following census record:
1930 Bowling Green Twp, Pettis County, MO, ED#2, page 168B
Dedrick, Perry, age 24, Head, born in MO
Dedrick, Edith, age 25, Wife, born in MO
Dedrick, Ella, age 7/12, Daughter, born in MO
Edwards, Martha, age 59, Mother-in-law, born in MO
This sure looks like it would be her. She has a child and her mother is living with her. Do you think this is her?
