I am looking to find more information about my g-g-grandfather, Johann Heinrich Vogt and his wife Rosina. I know they came from Prussia sometime during the 1850s, or a bit earlier, but don’t know where in Prussia from which they came. Their son Paul was my g-grandfather who was married to Dorothea Eickmann. Their daughter Anna Sophie was my grandmother who was married to Ernst Kohls. Any information on Johann and Rosina as well as other family is appreciated. Thank you.
