About Us / Cassidy Farm History: Cassidy Farm is a small farm located just north of Chelsea, MI. We grow heirloom vegetables of many varieties using only organic fertilizers and pesticides. The farm was started in 1853 by John Cassidy, a Scottish immigrant. It was originally a dairy farm, but they also raised corn, hay and many vegetables for their large family. The farm is on the state historic registry.
