There was a Margarette Groth married to Jurgen Frederick Hauschild. I don't know if her nickname was Maggie or not. She was born in Schleswig Holstein, Germany about 1845 & died in Sterling, Kansas on 19 April 1923. They had two sons -- Jerry Jurgen b. ca1866& John b. ca1874. Could she be the one your looking for? Other than what I've mentioned I don't much else about her.
