We've received the results of our first Y chromosome test for the Wickizer/Wickiser family. The numbers are posted on our personal website, www.millefleurs.tv, under the "Wickizer Genealogy" link. In isolation, the numbers don't mean much yet, although they do show that the family originated in western Europe (the R1b haplotype associated with the family indicates the underlying Celtic populations of Britain, France, Spain, and parts of Germany).
Our aim is to secure a sample test from a direct-line male descendant in each of the five branches of the Wickizer/Wickiser family; and also to get representative samples from several possibly related families in Germany, including the Weckessers and the Werkheisers.
The Werkheisers were located in the Easton, Pennsylvania area as early as the mid- to late 1700s. They left numerous descendants of various spellings, including at least one nineteenth-century family that changed its name to Wickizer (but is now extinct in the male line, and thus cannot be tested).
These questions should be easily answered with just a handful of tests. We're working with a professional genealogist in Germany to locate possible participants there from related lines.
In the meantime, please watch our website for further developments.
