Fuerstenau is one of the many wonderful little villages in Emsland that we visited while in Deutschland May 15-30. We visited nearby Freren and stayed two weeks in Wettrup. My great, great, great grandfather, Bernard Heinrich Feld, was from Herzlake (born about 1785) and his son, Johan Clemens Feld, was born in Langen (1829). Clemens emigrated to St. Louis in 1858 with his fiance, Maria Anna Schonhoff.
My records from 2001 show an 1864 marriage between Johan Gerhard Feld (b-1835, son of Johan Phillip Feld and Anna Adelheid Thunemann) and Maria Agnes Funke (b-1833, the daughter of Johan Gerhard Funke and Anna Angela Reson). These folks were from Hoehne near Furstenau.
