As of February 26, 2007, the Delano Kindred has nine participants in the Y-DNA testing project. We began with four men, each of whom had already been proven to be a descendant of a different son of Philippe Delanoy. We are pleased to report that project participation has more than doubled and, based on queries to the DELIST, interest in the project continues to grow as we receive more solid proof of the connections between male Kindred members with the surname Delano or Delanoy. (At this point, the Kindred is recommending only the Y-DNA test, which deals with proof of descent through the male line.)
Of the 9 subjects to date, 2 took only the 12-marker test; 5 took the 25-marker test; and 2 took the 37-marker test initially. The 12-marker tests have been upgraded to the next level One of the 25-marker tests has been upgraded to 37 markers, and one upgrade is pending. When an upgrade is requested, the 25 marker test automatically includes the 12 markers already tested and later upgrades encompass all the markers previously tested.
In eight out of the nine participants tested, most of the results indicate the presence of a common ancestor within the last 20 generations of the Delano/Delanoy line (or approximately 500 years). This is especially apparent in the results from the 25-marker test. As you can see from the chart at the end of this article, results are stated in terms of alleles, which are the repeat sequences of DNA tested. The number of repeats found at each marker are written in vertical columns under each DYS# (Marker designation).
The number of repeats enables participants to see how they match (or do not match) other subjects taking the Y-DNA test. Put simply, the more allele matches among the group tested, the higher the probability of a common ancestor. However, please note that exact matches of all markers are not necessary to prove the presence of a common ancestor. Mutations occur for various reasons over time.
Test Summaries:
12-marker test:
5 out of 9 participants: shows 0 mismatches, indicating an 87.07% probability of a
common ancestor within the last 20 generations
2 out of 9 participants: shows 1 mismatch, with a 58.61 % probability of a
common ancestor
1 out of 9 participants: shows 7 mismatches, indicating no probability of
relationship; 0% probability of a common ancestor.
25-marker test:
2 out of 6 participants: shows 0 mismatches, increases the probability of a
common ancestor within the last 20 generations to 99.12%
3 out of 6 participants: shows 1 mismatch, 93.74% probability of a common
ancestor
1 out of 6 participants: shows 2 mismatches, 84.83% probability of a common
ancestor.
One 25-marker upgraded test has been received but the results are still being analyzed. Further research is necessary to determine familial connections.
37-marker test:
2 out of 4 participants: tests show a tight relationship, with greater than 90%
probability of a common ancestor
1 out of 4 participants: shows 5 mismatches; further research must be done into a
common ancestor at least 16 or more generations ago.
Research is in progress.
1 upgrade is pending.
Important note: one participant in the 37-marker test is a proven descendant of Abraham Delanoy. The high probability of a common ancestor between the two men who took the 37-marker test provides a substantial reason to test European Delano/Delanoy males with documented proof of their descent. Additional European DNA testing is important; the new discovery of a connection with Abraham Delanoy needs to be explored with hopes of collecting further evidence and possibly learning of earlier generations prior to 1575 – again, a good reason to test a European Delano/Delanoy male subject. A paper trail on all new subjects will also prove helpful in tracking lines of descent.; however, such documentation is not mandatory.
Your project administrators will provide updates through both the DELIST mailing list and website.
