I have information on my husband's branch of Arns who emigrated from Durrn, Germany on October 28, 1850. They eventually settled in the Delhi, Ontario area of Canada via the Erie Canal. They had landed on February 14, 1851 in Hobochen, New Jersey, U.S.A. The family that emigrated from Durrn was Kornelius Arn (born 1795) his wife Karoline Wilhelmene Bossert Arn (born 1797) and nine or ten of their seventeen children. The remainder of the children died young and are buried in Germany.
Kornelius had been a farmer in Durrn in 1836 and a 'burgomaster' in 1837. His grandfather is 'supposedly' a Martin Arn (born 1696, died 1753, married 1742(second wife) Regina Catharina).
Two of Kornelius Arn's siblings were 'supposedly' named Johann Jacob and Daniel.
Kornelius Arn's great grandfather was 'supposedly' Johannes Arn who was born circa 1646 in Switzerland, died May 23, 1702 Durrn, Germany & married Katharine Klumpp.
Any information on these distant branches would be most welcome.
