At present, the Santry/Sauntry surname project has just four members who have tested to 67 markers. This a small sample from which to extrapolate, and it is not, as yet, possible to identify off-modal mutations. Consequently, the following analysis must remain provisional, until such time as more Santrys/Sauntrys get tested.

All who are currently members of the Sauntry/Santry surname project appear to share a common ancestor within a genealogical timescale. Four members have tested to 67 markers; these are within Genetic Distance (GD) of 10 of one another over 67 markers. FTDNATiP calculates the probability that these individuals share a common patrilinear ancestor within 24 generations to be in excess of 62%.

FTDNATiP calculates the most closely related members to be kit #236809 and kit #175228: the probability that these two members shared a common patrilinear ancestor within 8 generations is 60.8%; that they share one within 9 generations, 72.37%; and that they share a common ancestor within 10 generations, 80.8%; this rises to greater than 97% within 12 generations (i.e., positing 30 years per generation, greater than 60% probability of a MRCA ancestor within the last 240 years or so; greater than 72% of a MRCA within 270 years or so; greater than 80% of a MRCA within 300 years or so, and greater than 97% of a MRCA within 360 years or so).

The most distantly related appear to be kit #169156 and kit #248353 (FTDNATiP calculates their MRCA at 51.89% within 22 generations, and 62.91% within 24 generations – i.e. at greater than 51% probability that they share a common patrilinear ancestor within the last 660 years or so, and at greater than 62% that they share a common patrilinear ancestor within the last 720 years or so).

The project includes one member who has not tested beyond 37 markers, over which he is a GD of between 4 and 9 of all other members, and over which FTDNATiP calculates the probability of sharing a common patrilinear ancestor  with all other project members to be in excess of 68% within 24 generations (i.e. within 720 years or so).

All current members are predicted to be haplogroup R-L21 (R1b1a2a1a1b4), on the basis that their STR results of all are within GD of 10 over 67 markers from kit #236809, who has been tested L21+.

The earliest known ancestor of kit #169156 is his second-great-grandfather, William Sauntry/Santry of the townland of Dromkeal in the parish of Skull, in the barony of Carbery West (East Division), county Cork, whose widow, Ellen Sauntry/Santry nee Harrigan/Horgan,and eight children emigrated to Newcastle, New Brunswick, Canada on or about 1854.  This project member does not share common ancestry with any other within at least four generations.

Over 67 markers, kit #169156 is GD of 7 from kit #236809, GD of 9 from kit #175228, and GD of 10 from kit #248353. (#169156 and #236809 have not shared a common ancestor in at least six generations, on this basis, FTDNATiP calculates these members’ MRCA at 63.69% within 14 generations, 70.42% within 15 generations, 81.21% within 17 generations, 91.32% over 20 generations, and 97.31% within 24 generations; #169156 and #175228 do not share a common ancestor in at least five generations, and on this basis FTDNATiP calculates their MRCA at 51.43% within 15 generations, 64.89% within 17 generations, 70.73% within 18 generations, 80.37% within 20 generations, 90.02% within 23 generations, and 92.18% within 24 generations; on the basis that #169156 and #248353 do not share a common ancestor in at least four generations, FTDNATiP calculates their MRCA at 51.89% within 22 generations, and 62.91% within 24 generations.)

The earliest known ancestor of kit #236809 is his fourth-great-grandfather, William Sauntry/Santry of the townland of Currihevern East, in the parish of Abbeymahon, in the barony of Ibane and Barryroe, county Cork. Consequently, this project member is known not to share a common ancestor with any other member of the project within the last six generations. This member is confirmed to be haplogroup R-L21 (R1b1a2a1a1b4).

Over 67 markers, kit #236809 is GD of 2 from kit #175228, GD of 7 from kit #248353, and GD of 7 from kit #169156. (FTDNATiP calculates the MRCA of #236809 and #175228 at 60.8% within 8 generations, 72.37% within 9 generations, 80.8% within 10 generations, 91.03% within 12 generations, 97.32% within 15 generations, and 99.24% generations; FTDNATiP calculates the MRCA of #236809 and #248353 at 63.87% within 17 generations, 74.99% within 19 generations, 83.45% within 21 generations, and 91.71% within 24 generations; FTDNATiP calculates the MRCA of #236809 and #169156 at 63.69% within 14 generations, 70.42% within 15 generations, 81.21% within 17 generations, 91.32% over 20 generations, and 97.31% within 24 generations.)

The earliest known ancestor of kit #175228 is his third-great-grandfather, Jeremiah Sauntry/Santry of the townland of Burgatia, in the parish of Ross, in the barony of Carbery East (West Division), county Cork. This member’s second-great-grandfather, John Sauntry/Santry, moved to the neighbouring townland of Knocknagappul, in the parish of Rathbarry, barony of Ibane and Barryroe, and his great-grandfather, Jeremiah, emigrated to the US and settled in Montana. Consequently, this project member is known not to share a common ancestor with any other member of the project within the last five generations.

Over 67 markers, kit #175228 is GD of 2 from kit #263809, GD of 8 from kit #248353, and GD of 9 from kit #169156. (It is known that #175228 and # 236809 do not share a common ancestor within six generations, on which basis, FTDNATiP calculates the MRCA of these two members at 60.8% within 8 generations, 72.37% within 9 generations, 80.8% within 10 generations, 91.03% within 12 generations, 97.32%within 15 generations, and 99.24% generations; on the basis of not sharing common descent within five generations, FTDNATiP calculates #175228 and #248353 at 50.39% within 15 generations, 63.87% within 17 generations, 74.99% within 19 generations, 83.43% within 21 generations, and 91.71% within 24 generations; FTDNATiP calculates the MRCA of #175228 and #169156 at 51.43% within 15 generations, 64.89% within 17 generations, 70.73% within 18 generations, 80.37%within 20 generations, 90.02% within 23 generations, and 92.18% within 24 generations.)

The earliest known ancestor of kit #248353 is his second-great-grandfather, Patrick Sauntry/Santry of the townland of Gurranigoleen, in the parish of Kilkerranmore, in the barony of Ibane and Barryroe, county Cork. He is known not to share a common ancestor with any other member of the project within the last four generations.

Over 67 markers, kit #248353 is GD of 7 from kit #236809, GD of 8 from kit #175228, and GD of 10 from kit #169156. (It is known that #248353  and #236809 do not share a common ancestor within six generations, on which basis, FTDNATiP calculates the MRCA of these two members at 63.87% within 17 generations, 74.99% within 19 generations, 83.45%within 21 generations, and 91.71% within 24 generations; It is known that #248353 and #175228 do not share a common ancestor within six generations, on which basis, FTDNATiP calculates the MRCA of these two members at 50.39% within 15 generations, 63.87% within 17 generations, 74.99% within 19 generations, 83.43% within 21 generations, and 91.71% within 24 generations; on the basis that #248353 and #169156 are not known to share a common ancestor in at least four generations, FTDNATiP calculates their MRCA at 51.89% within 22 generations, and 62.91% within 24 generations.)

The earliest known ancestor of kit #112894 is John W Taylor. Taylor is known to be a maternally-inherited surname in this line, and the paternal line surname is unknown. The match with Santry/Sauntry raises the possibility of paternal Santry/Sauntry lineage. This member is known not to share a common ancestor with any other member of the project within the last three generations. Over 37 markers, kit #112894 is GD of 4 from kit #169156, GD of 8 from kit #236809, GD of 9 from kit #248353, and GD of 9 from kit #175228.
