There is another family lineage of Kruizenga's in the Greater West Michigan area.  A Derk Kruizenga emigrated to the Spring Lake (near Grand Haven) area with his wife.  Knowing that not all Kruizenga's are related, due to the close proximity and the common name(s), I had to look into the matter.

The Spring Lake clan originates in the Groningen Province, around Warffum and Uithuizermeeden.   I traced the Spring Lake Derk Kruizenga back into the 1700s. 

Derk Kruizenga (b. 1856 at 't Zandt) - father: Jan Pieters Kruizenga
Jan Pieters Kruizenga (b. 1814 at Uithuizermeeden) - father: Pieter Folkerts Kruizenga
Pieter Folkerts Kruizenga (b.1791 at Warffum) - father: Folkert Jans (note: on marriage certificate - name spelled 'Kruizinga')

Folkert Jans died prior to 1799 when his widow, Auke Pieters, remarried Jacob Jans of Uithuizen.  The family name was not yet chosen in his time.  The first instance of the surname 'Kruizinga' being used, that I have found, is on Pieter Folkerts marriage certificate.

A descendant of this Derk Kruizenga contacted me this week to inquire whether our two Kruizenga clans were intertwined.  It does make some sense seeing that both our lines have a common city: 't Zandt.  However, upon tracing the Spring Lake clan's genealogy, it is apparent that there is no common relation.  That both Kruizenga families ended up in 't Zandt is a fluke.  Yes, it is likely that they knew each other - assuming that both Kruizenga clans attended church.  But friendship is as far as it goes.

Elaine, my contact, writes that Derk Kruizenga emigrated to Spring Lake with his newlywed bride but then migrated to Sioux County, Iowa, before 1883.
