I am searching for any sibling descendants of my ancestor Johann Carl Arend born circa 1735 in Wusterhausen Brandenburg.He may have lived in Westerhausen before arriving in Ceylon(Sri Lanka) which was then a Dutch Colony in the mid 1700's.There was a name change that also took place at some point in his life.The name his descendants bear to this day is Arndt. I am looking for any sibling descendants of this gentleman who could be living somewhere in Germany.Please,please get in touch with me.
