Im looking for parents of Louisa Caroline Jahnke Gralow, born 9-29-1823 in Gross Sabow Kreis Naugard Pommern. She married August Frederich Gralow (also looking for his parents) 1827-1902, in 1856 in Prussia. They emmigrated to WI. in 1883 on the Hohenzollern out of Bremen. Any help with this would be greatly appreciated!
