After about 6 months of rigorous testing of my Y-DNA strand, my male ancestor's Y-DNA Haplogroup has been determined without a shadow of a doubt due to the mutation M253.  This places the Kruizenga/Kruizinga clan inside the Haplogroup I1.  My Y-DNA will match every male descendant of Jacob Cornelis Kruize regardless of family line.  We all share the same Y-DNA passed from father to father through the generations.

In human genetics, Haplogroup I1 is a Y chromosome haplogroup occurring at greatest frequency in Scandinavia, associated with the mutations identified as M253, M307, P30, and P40. These are known as single nucleotide polymorphisms (SNPs). It is a subclade of Haplogroup I. Before a reclassification in 2008,[1] the group was known as Haplogroup I1a.[2] Some individuals and organizations continue to use the I1a designation.

The group displays a very clear frequency gradient, with a peak of approximately 40 percent among the populations of western Finland and more than 50 percent in the province of Satakunta,[3] around 35 percent in southern Norway, southwestern Sweden especially on the island of Gotland, and Denmark, with rapidly decreasing frequencies toward the edges of the historically Germanic sphere of influence.

Earlier in the year I received the results for my Y-DNA 67 test which are posted below.  I am now waiting for absolute certainty on the Haplogroup my DNA places me into.  This DNA is the same carried by all male members of the Kruizenga family that are direct descendants of Jacob Cornellis.

The results given above have no direct matches in either the Family Tree DNA or Ancestry.com databases.  Not yet.

As I was writing this I received confirmation on my descendants Haplogroup type.  What is a Haplogroup?

The haplogroups are the major branches on the Y chromosome tree, defined single nucleotide polymorphisms (SNPs), which have accumulated along different lineages as Y chromosomes are passed from father to son over many generations. All haplogroups ultimately descend from a single Y chromosome carried by a male that lived in the distant past. The topology of the Y chromosome tree can be reconstructed by typing mutations in different human populations – as more SNPs are discovered (e.g., M254), the structure of the tree changes. Originally, the Y Chromosome Consortium (YCC) arbitrarily defined 18 haplogroups (A-R), which represent the major divisions of human diversity based on Y chromosome SNPs. Currently there are 20 haplogroups (A-T). In turn, each of these major haplogroups has numbered subgroups, or subclades, that are named with alternating letters and numbers.

My descendants Haplogroup type has been confirmed as: type I1.

Haplogroup type I1 is also known as the "Stonemasons".  Our type is found predominantly in Norway, Sweden, Denmark, and parts of Finland.  We eventually migrated down into what is today Northern Netherlands where we established roots.  If we could trace our ancestry back far enough what we would find is an original ancestor that emigrated into the Netherlands from one of these northern areas.
