Betty, Johann is the most usual first name in Prussia in the 19th century. It means simply Johannes, one of the evangelists. Heinrich was used in Lower saxony up to the 1950s. Johann Heinrich Christian is a usual combination, I have some ancestors in Lower Saxony, former kingdom Hannover, with this combination. Do you know which Fricke came to New Orleans and when? In Lower Saxony Fricke is a wellknown familyname and maybe we can find relations to my family (I am living 50 km south of Hannover).
