Just go to Weidenaar, Dirk Hessels and click on the parents’ names. The site is in English.

There are a number of Weidenaar’s who went to the USA. They are all related to each other (and therefore also to Trijntje/Catherine)
The closest relative of Trijntje/Catharine who left for the USA I could find is her uncle, Eelke Weidenaar, born 14 Dec 1832. He left with his wife Lieuwkje Bolt and son Jan for the USA-unidentified region on 29 Mar 1882. their son Jurjen had already crossed on 07 Apr 1881.

I hope I have helped you a bit in your search for your ancestors....

Kind regards,
Marianne
