*The marker value at Sequence No. 12, designated DYS 389 b, represents the difference after subtracting from DYS 389-II, the marker actually tested at that position, the value for DYS 389-I, tested at sequence number 10. The two markers overlap, and the subtraction prevents a mutation in the overlapping portion from being shown twice; a mutation in the overlapping portion will show only for marker DYS 389-I. The value subtracted for all the samples was 14, the modal value, but is not shown here because it was the same for all.  Only BAL 1, with a value of 30 before subtraction, exhibits a mutation in the non-overlapping portion of DYS 389-II, where all the other samples showed 31.

Of five samples tested at 67 markers, four show no variations from modal values at markers #38 to #67. Violet shading of sample numbers designates descendants of four known brothers, first of record in western Pennsylvania in the late 1700s. Their close matches are consistent with that relationship.

The allele value “19” at marker #28, YCA-IIa, is found in all known descendants of Francis Baldwin, one of the three 1682 immigrant brothers to Chester County, Pennsylvania, and in one descendant of a second brother Thomas, through his son Joseph. Thus it appears to be ancestral to both brothers, as inherited from their father William, who lived and died in Oxfordshire, England. However, no sample is yet available representing the line of the third brother John, which could confirm this conclusion.

The value “17”at that marker appears in only one sample with a known origin, from a line descended from the immigrant brother Thomas through his son Anthony. Thus it appears to be a recent mutation distinctive to descendants of Anthony. That conclusion that it is a recent mutation is reinforced by the fact that the value “17” for this marker is quite rare in Haplogroup I,  occurring in less than 0.5% of samples, but remains  subject to further confirmation when additional samples become available.

This same distinctive “17” appears in the lineages of four brothers, first of record in western Pennsylvania in the late 1700s, but whose parents are unknown, and for Eli Baldwin, born ca 1790 and a life-long resident of Delaware County, Pa., whose parents are simiilarly unknown.  The DNA, when considered with the record evidence, points toward their descent from Thomas through his son Anthony.

BAL 54 and 61 are known to be closely related to each other, and the DNA results are confirmatory. The value “17,” found in a known descendant of his brother Thomas, and in other matching samples with no record link to any of the immigrant brothers, is presumed to identify the lines of Thomas and the third brother John. No sample from John’s line has yet been tested to verify its presence there, but whether or not it occurs in John’s line, all the “17” samples tested are tentatively thought to represent Thomas’s line, because there  are no gaps among known John’s descendants where the unlinked branches might tie in.
