I don't know if our families are connected, but my Feldt/Felt/Feld family is also from Emsland:
Johan Philipp Feld , born between January and June 7, 1826, in Drope (parish of Lengerich), to Bernhard Albert Feld and Catharine Aleid Frese (aka Froese). He emigrated to the USA in 1847, arriving in New Orleans on Dec 30, 1847, on the ship Epaminondas. Johan Phillip married Anna Gesina Brand on Jul 22, 1851, St. Louis, MO. She was the daughter of Johann Bernard Brand and Maria Gesina Boestcher (aka Poetker). Anna also emigrated from Emsland. She was born July 29, 1826, in Rull by Dalum (in the parish of Gross Hesepe).
Any information appreciated.
