Joseph Eifert was the son of Michael Eifert, a German immigrant. He was born in Knox County, Ohio and died in Mercer County, Ohio. He married Sophia Weis and was the father of eight children.
Around 1860, Michael Eifert and his sons, Joseph and Victor, purchased land in Mercer County, Ohio. They were part of a large westward movement of German immigrants likely seeking better land, freedom from anti-Catholicism and the ability to give their children a Catholic education.
