Hi Regina,
My wife is also a descendant of Johan Hvezda (Wisda) thorough Joseph Wisda, the brother of James. Joseph had a daughter, Jennie D. Wisda born 1875 in Defiance Ohio. Jennie is my wife's grandmother. I assume that that the Wisdas emigrated sometime around 1860 because Mary and Anna were born in Ohio whereas the older children were born in Bremen. Would love to email with you regarding the Wisdas.
Paul
