Robert Courtney 1640 “The Immigrant”
Anyone wishing more information can email me at firstname.lastname@example.org
There are literally hundreds and hundreds of pedigrees published that declare that Robert Courtney 1695-1751 of Onslow, North Carolina is the son of Reverend John Courtney and grandson of Robert Courtney 1640-1684 “The Immigrant” of Virginia. Most of these assumptions are falsely based on the book entitled King and Queen County, Virginia by Rev. Alfred Bagby 1908. Like so many genealogical books written around the turn of the last century many of the conclusions were in error and are gradually being corrected. For an excellent treatise concerning these early Roberts please refer to the article:
WHO WAS ROBERT COURTNEY’S FATHER? By Chuck Courtney – ©2016.
Descendants of Robert 1640 “The Immigrant” include
1. Reverend John Courtney 1670-1727, no known descendants.

Enter DNA testing, specifically YDNA which traces the Y chromosome in males going back from son to father to father. The Y chromosome is very slowly mutating allowing a wonderful tool to compare men going backwards from today for thousands of years.
The first male Courtney received his YDNA results from FamilyTreeDNA.com in late August of 2002. The word has spread and DNA testing has gradually become a commonly used tool in the genealogists tool kit.
Where do we stand today?
It has always been a goal of the Courtney DNA Project to gather together members of similar genealogies based upon sound DNA evidence. So, in reality, “genetics trumps written histories”.
There has been a concerted effort made by members of the project to obtain DNA samples from descendants of Robert Courtney 1640-1684 “The Immigrant”. What was needed was to find descendants from all the sons of “The Immigrant” and to verify that the lineages were accurate.
Kit # 594183 has a documented lineage from Phillip Courtney 1723-1809, the son or grandson of Robert 1640 “The Immigrant”. He matches the Courtneys (O'Cournane) of Kerry County, Ireland.
The STR mutation values are displayed on the Courtney DNA Project - Y-DNA Classic Chart, scroll down to Group 24.
The SNP mutation R1b-A809 defines this branch of Courtneys (O'Cournane) of Kerry County, Ireland. On the above chart, members of each group have tested positive for the A809 SNP and two members have taken the Big Y test.
