Dear marpost65,

The 1855 marriage record (21 Jun 1855, nr. 36) gives the names of the parents:
Hendrik Post and Dirkjen Knol for the groom
Hendrik van Bruggen and Geesje Westera for the bride.

If you type in these names in http://www.genlias.nl, you'll find that van Bruggen and Westera were married on 15 Aug 1833 in Kampen (marriage record nr. 48). The dates and places of their birth, and the names of their parents are listed.

The same goes for the Post-Knol marriage, on 2 Nov 1821 in Zwollerkerspel, marriage record nr. 24.

Using http://www.genver.nl, you can look up the actual marriage records. Be sure to also look up the annexes (huwelijkse bijlagen) since they usually contain much additional information, like the births of the bride and groom and the deaths of their parents, if applicable.

Other births and deaths can also be found using http://www.genver.nl, click on "Overijssel" (Kampen and Zwollerkerspel are in that province), then e.g. Kampen.

Indexes are found in the files called "index BS" (index civil registry) or "tienjarige tafel" (10-year table).

Good luck!
