Hi Kathy, I have found the following information about Jurgen at genlias.nl it is a Dutch site that can be converted to English to trace by your family who was born, married or died in the Netherlands.
Jurgen Dijkstra was actualy born in Wymbritseradeel, Neth on July 24, 1837.His family is as follows: Father: Tjerk Jurgens Dijkstra Mother: Corneliske Minnes Walsweer
He also had 3 Sisters and 1 Brother, all of which were born in Wymbritseradeel.
Sisters: Wypkien Dijkstra, B. June 21, 1839 Trijntje Dijkstra, B. July 3, 1841 Antje Dijkstra, B. Jan 5, 1846
Brother: Minne Dijkstra, B. Oct 2, 1843
His Father married Corneliske on August 30, 1836 in Wymbritseradeel, Neth.He then passed away at only 30 years of age on March 15, 1846.Corneliske later remarried and had 2 more children.
I hope that this information in some way helps you.You can do your own searching at the genlias.nl site as well to trace back other family that may have been born in the Netherlands.Also, as far as Jurgen coming to the Unites States he must have come over before they started logging the information in at the Ellis Island site as he is not listed.They only trace back to 1892.Good luck with the remainder of your search and if you need any help or have questions you can contact me at firstname.lastname@example.org.
God Bless, Evonne Moody P.S. I also have the Dijkstra surname in my family tree but they are not related to Jurgen that I can tell.
