G-G-Grandmother was a Marie Mateusczyk/Matuszek/Matheuszik married a Ludwig Kownatzki in the mid/late 1800s. Lived in the area of Duttken (Kr Lyck) East Prussia. Ludwig was still alive in 1908 when daughter Charlotte immigrated. Unsure about Marie. Know nothing about the Matuszek family, however. Am interested if there is anyone else with family in the same area.
