All males surnamed Wellhausen, Wilhousen, Welhouse, Willhouse, Welhuis, Wellejus, Amsler, Amzler, Flato, Flatow, Flateau, Fricke, Fricker, Frick, Frich, Fritsch plus similar spellings in Germany, the Netherlands, Denmark, America, Europe, and around the world, are cordially invited to take the Y-DNA test and join this Wellhausen-Amsler Family History Y-DNA Study. Female Wellhausen-Amsler-Flato-Fricke descendants and other male Wellhausen, Amsler or Fricke descendants not having the Wellhausen, Amsler, Flato, or Fricke surname can easily participate and advance the Study by recruiting their Wellhausen-Amsler-Fricke-surname father, brother, uncle, cousin, nephew, etc., to take the test representing their common Wellhausen-Amsler-Fricke line. Another way for a descendant of any of these surnames to participate would be to order a FTDNA Family Finder test - either male or female, and either surname or non-surname descendant. NOTE: The Wellhausen - Amsler study has limited funds available from time to time to contribute toward testing costs for a Wellhausen or Amsler line not previously tested and for special lines where a confirming test is being sought. Please inquire if the contribution funds are available for a test on your Wellhausen or Amsler line. Generally, the more markers tested, the better the bang for the buck in tracing detail. The starter 37-marker Y-DNA test is a very useful test. The 37m has enough marker detail to avoid false positive matches and provide minimal specific detail sufficient to tell whether two matching testers are probably related. The 67 and 111-marker tests provide progressively more marker data than the 37-marker at a smaller per-marker cost and achieving greater accuracy for long-range tracing. The most powerful and most accurate test for long-range tracing is the Big-Y 700, which can be bought on special or holiday sales from time to time at a substantial discount. But we're always glad to have a 37-marker, and it can typically be upgraded as a Christmas or birthday present to yourself without the need for a new sample.
