CONN GROUP #1 (Highlighted in yellow on the chart): REV. HUGH CONN, THOMAS CONN I, ‘FAYETTE’ GEORGE CONN(Kits #17900, #24279, #23512, #14461, #N69088, #182927, #151630 and #19863) all with roots in Ireland 1685-1736, are y-DNA linked to JOHN CONN (Kit #61549)born 1754, of Ayrshire, Scotland. Participants in this group each have an EXTREMELY RARE “value” of 16 at marker 388 when a value of 14 is found in the first marker, #393. Bennett Greenspan of FamilyTree DNA had this to say about the 16 at DYS388: “The 16 at DYS 388 is not an unknown marker, but it is not common. 16 at DYS 388 is found in 2.34% of our world wide database. However when I search that database with the 14 in the first marker (DYS 393) and the uncommon 16 at DYS 388 those two markers bring back 36 matches of 21,411 samples...6 of them are CONNS. Are they related? Yes they are. The man in the middle (Thomas I, Kit #19863) is the missing man in the puzzle...the man who is in between each of the other 5 test takers. This is why sometimes it is good to NOT stop testing too soon.” Hugh (Test Kit #23512) matches Thomas I (#19863) at 35 out of 37 markers with just one 1-step mutation at a slow-moving marker and one 1-step mutation at a fast-moving marker. 'Fayette' George #69088 matches this Thomas I (#19863)100% at 37 markers. The fact that the y-DNA of John Conn, b1754, of Ayrshire, Scotland (Kit #61549) matches this group indicates that researchers of Rev. Hugh, Thomas, and 'Fayette' George Conn should be looking possibly in Ayrshire, Scotland for their roots. However, Test Kit #61549 should be expanded to the full 37 markers just to be certain they are a true match. The rare value of 16 at marker 388 neatly ties them all in a unique and very identifiable family group for us. Unfortunately, y-DNA cannot yet tell us the exact relationship between Rev. Hugh Conn, Thomas Conn, 'Fayette' George Conn and John Conn. It can only tell us that they are very closely related. Though y-DNA cannot answer all of our questions, it can tell us to follow each of these lines to find their origin, possibly in Ayrshire, Scotland where John Conn, b1754, has pointed through the clue left by his y-DNA. 

CONN GROUP #3 (Highlighted in mint green on the chart):  JESSE WILSON CONN b~1788 of Virginia (Kits #24411 & #17649): Four of our participants have matching y-DNA markers, confirming their paper trails leading back to two sons of Jesse Wilson Conn. Some of them did not know each other before participating in the y-DNA testing. Some researchers are surprised to learn that Jesse Conn's markers do not match those of Rev. Hugh Conn. More participants from other branches of Jesse's tree should be tested. Although Jesse Conn and Levi Conn were living next to each other, their markers do not match. See Levi Conn results in Group #5 below.

CONN GROUP #4 (Highlighted in light blue on the chart): EMMANUEL CONN, (Kits #17641 and #36391): One participant (#17641) identifies his ancestor as “Emmanuel Conn, b~1809, possibly Maryland” and the other (#36391) as “Emmanuel Conn of Fayette County, Pennsylvania”. The two participants match 24 out of 25 markers with a 3-step mutation at just one fast-moving marker, indicating they are definitely related. Some thought that the y-DNA markers for Emmanuel Conn of Fayette County, Pennsylvania might have matched “Fayette” George Conn, but the markers show they are not related.

CONN GROUP #5 (Highlighted in pink on the chart):
LEVI CONN b~1790, Virginia (Kits #38934 and #36161): Testing at 25 markers indicates the two participants are somehow related with the markers matching 22 out of 25, with a 1-step mutation at a slow-moving marker and two 2-step mutations at two fast-moving markers. These mutations will identify two distinct branches of the family tree. We expect they will match their 26-37 markers if they ever expand their test. Although Jesse Wilson Conn and Levi Conn were living next to each other, their markers do not match. See Jesse Wilson Conn results in Group #3 above.

CONN GROUP #6 (Highlighted in plum on the chart):  Two participants trace their lineage to Archibald and George Conn of West Chester, PA.  while in the same time period #513616 has a paper trail to William Conn of Somerset, NJ.  JOHN CONN (b~1805, PENNSYLVANIA or OHIO) matches ROBERT CONN (OF COUNTY ARMAGH, IRELAND 1834), (Kits #19247 and #24175).   A most surprising result is the case of two participants who match 23 out of 25, one living in the U.S. and the other in Australia. The U.S. participant traces his lineage to John Conn, born about 1805 in Pennsylvania, yet the Australian participant traces his ancestry back to Robert Conn who was in Baltylum Armagh, Ireland in 1834. This kind of match is Y-DNA science at its best! These two gentlemen would never have found one another without this test! They are separated by just two 1-step mutations in fast-moving markers indicating they should be related. Matching participant #109071 has not shared his lineage with us.

CONN GROUP #7 (Highlighted in orange on the chart):  This represents the Conn line from Aberdeenshire, Scotland.  It is important to note that the yDNA tests of these CONN males from Aberdeenshire debunk W. Clark Conn's fantasy publication "The Scottish and Irish Background of the Rev. Hugh Conn of the Colonial Clergy of Maryland".  The manuscript created by my husband's cousin, Clark, is written in a scholarly fashion, impressing the reader that his information surely must be correct.  BEWARE!  Note that Clark's own yDNA test falls into Conn Group #1 from Ayreshire, Scotland - not into Conn Group #7 from Aberdeenshire as Clark had expected.  The results of Clark's yDNA test were difficult for him to accept.  For many years, many of Clark's cousins were trying to show Clark that his published research was incorrect.  He refused to believe it until yDNA came along and proved the oral history and paper trails leading to Ayreshire, Scotland - not Aberdeenshire, Scotland - were correct.
