Thanks very much for your response. My Ancesters went to South America . My Great Great Grandfather married a lady who was mix race (Native Indian and Dutch). Her Family name is De Rycke. I would it very difficult to track the De Rycke name in Holland. Could you recommend a good source in Holland for tracing names and immigration details.
There was a hendrick Van Cooten who travelled to Guyana on a Royal assignment.
Are you aware of a town in Germany called Kothen? It would be interesting to know if Cothen in Holland was ever inhabited by Germans from Kothen.
