Your mention of Leunichor is one of the many bad translations that have found there way into genealogical records. Willem Jansen Traphagen has been poorly indentified by researchers who assumed everyone in New Netherlands or those who tended to lump settlers together without proper research. Some records say he was born in France but that is because many of the founding settlers of Bushwick were French so they 'assumed' Willem was too.
Facts. Willem or Wilman or Wilhelm Traphagen was born in Lemgo in Lippe, GErmany between 1615 and 1625 and made his way to Amsterdam by 1647. By 1652 he was living in New Amsterdam. He was from an ancient family in Germany dating back to the early 1400's but his ancestry can be traced back no further (with accuracy) to his grandfather.
I am getting ready to hire a professional researcher in Germany check records in the Lemgo stadtarchiv that aren't available on LDS microfilm and hope to find more information on his family there.
So despite what you read in a lot of pedigrees, believe me was born and raised at Lemgo.
