Known Persons with DYS19<=9


We have compiled the available Y-DNA data for all known persons tested who exhibit the low DYS19 STR marker value of 9, or less. The various individuals have tested at differing labs, with different sets of markers. Therefore, one must be cautious in making comparisons. Given that caveat, see the genetic distance cross-matrix and Y-DNA data of these 24 persons. We used McGee's tool to calculate Time (Generations) to Most Recent Common Ancestor, in generations, at 50% and at 95%.

Genetic distance cross-matrices and Y-DNA data for the 14 members of the DYS19<=9 Project at FTDNA appear herein:
matrix - 14 members with >= 37 marker tests
matrix - 8 members with >= 67 marker tests
matrix - 6 members with 111 marker tests

The Swiss subgroup of eight known-related persons among these members presents interesting data showing rather few mutations, considering the 20 generations and 650 years since the common ancestor. More markers tested for other members would help to make the story clearer!

The actual TMRCAs within this Swiss subgroup, using the known genealogical paper-trails, are displayed in this table. A comparison of this actual paper-trail data with calculated predictions is presented here.

We do not have enough data to extend those charting techniques to the other subgroups. At least, we can offer a simplified table of mutations, relative to the modal, for the Italian group.

Published data for DYS19<=9 has been gathered here from multiple sites for ease of analysis. A degree of anonymization has been applied. Ancestral surnames (or variants) include: Beasley, Castrignano, Cellier, Chiffelle, Cipelli, Ciullo, Galliano, Junod, Koenig, Ragucci, Ramondino, Raymond, Rossetti, Schiffley, Tschiffeli, Villano, Visconti, Willoughby.
