In January 1970, they moved to the new home they built in Key West. They turned the 65 acres near their home into Twin Ridge Subdivision where more than 100 families live today. In partnership with their son, Dan, they developed another 47 acres near the intersection of Highway 151/61 and 52 into commercial business lots which became Dubuque Southgate Development Ltd.

They donated a parcel of property to the Key West Fire Department in 2005 for the construction of a new fire station, parking lot and recreation area.

Grace, from a very young age played piano and loved to entertain anyone who would listen. She was an organist at St. Joseph’s for many years, playing for weddings, funerals and other events. She also played at the Moracco Supper Club, The Chateau Supper Club, the Swiss Valley Chalet and the Grand Tap in Dubuque, as well as the Log Cabin in Galena, Ill., over the years, plus several local nursing homes.

At the age of 43, she went back to school to become a nurse, a career she enjoyed for 23 years until her retirement in 1993 at the age of 68.

She was a member of the Dubuque County Board of Health for more than 20 years. She was vice chair of the Farm Bureau Women’s Committee and was named “Mother of the Year” in May of 2003 by the Dubuque County Farm Bureau.
