    Here's a short, redacted summary of some of the evidence from DNA testing.

    Big Y-700 match (Family Tree DNA of Houston, Texas): SNP FGC36982; 757/758 STR match (99.868%) to a man with my surname (Stevens) who has an excellent, well-documented paper trail to Augustine Stevens and his wife Sophia Young through their son, Amos H. Stevens (b. 1778). Based on this Y-DNA match, Family Tree DNA estimates that there is a 99% chance that this documented descendant of Augustine Stevens and I share a common Y-DNA ancestor within the last eight generations. (Augustine is 6 generations back from him and 7 generations back from me.)

    Y-DNA matches (Family Tree DNA of Houston, Texas) to two Y-chromosome descendants of Benjamin Stevens Sr. (1737-1811) of Fayette Co., PA, identified by professional genealogist Joan Peake as probably a brother of Augustine Stevens. One of those matches has been Big Y-500 tested: terminal SNP FGC36974, which is just upstream of FGC36982. He is a 106/111 STR match for me (626/634 STRs based on his Big Y-500 and my Big Y-700: 98.7%). The second of those descendants of Benjamin Stevens Sr. is a 104/111 Y-DNA STR match for me (he has not had any Big Y testing).

    Note: Augustine Stevens is mentioned in the will of Samuel Stevens, documented brother of Benjamin Stevens Sr. Augustine was also a witness to the will and signed it.

    Y-DNA match (Family Tree DNA, Houston, Texas) to a documented Y-DNA descendant of Obadiah Stevens (b. 9 Oct 1787), who was born and lived in Fayette Co., PA, at the time when Augustine Stevens and Sophia Young lived there and who, as this descendant’s Y-DNA matches prove, was closely related to Augustine. Big Y-500 tested. Terminal SNP PF5064, one step downstream of FGC36974. 107/111 Y-DNA STR match (666/670 STR match based on his Big Y-500 and my Big Y-700: 99.4%).

    Autosomal DNA:
    I have seven autosomal DNA matches to descendants of Amos H. Stevens, best documented son of Augustine Stevens and his wife Sophia Young: one via Amos H.’s son Amos Stevens (b. 1815); two via Amos H.’s daughter Nancy Stevens (b. 1801); three via Amos H.’s son Daniel Stevens (b. 1822); and one via Amos H.’s daughter Hannah Stevens (b. 1813).

    One autosomal DNA match of 17.4 cMs across 1 segment (AncestryDNA) to a descendant of Benjamin Stevens Sr. (1737-1811). She is the 4th great granddaughter of Benjamin Stevens Jr. (son of Benjamin Stevens Sr., ancestor of the two Y-DNA matches mentioned above) and his wife Sophia Peairs via their daughter Elizabeth Stevens (b. about 1812), who married William Boyd.

      It's kind of aggravating being the one person in my group of Y-DNA matches and family members who is on fire for genetic genealogy and genealogy in general. When I post on my project's activity feed and elsewhere (like here) I feel like I'm talking to myself. Sigh . . .
