17 December, 2009 YDNA 37 marker results were received for Sowinski project member 165618. 165618 matches 61198 at all 37 locations, and matches 164632 at 36 out of 37 locations. These results conclusively identify a distinct third branch of descendents from the 1819 marriage of Jakub Sowinski and Magdalena Musial. 23 November, 2009 YDNA 37 marker results were received for Sowinski project member 164632. 164632 matches member 61198 at 36 out of 37 locations. This strongly supports the paper research that suggests the two are fourth cousins each descending from the 1819 marriage of Jakub Sowinski and Magdalena Musial. The variance occurs at DYS 570 which is considered the least stable marker among the 37 markers measured. Member 164632 has a value of 20 repeats at DYS 570 while 61198 has a value of 21. The modal value for this marker within haplogroup I1 is considered to be 19 (see footnote). Hamilton, Gordon, Distribution of Repeat Values at Various STR Sites for Haplogroup I1
