Duinbar/Cokburn on 1654 map together; http://maps.nls.uk/view/00000383#zoom=5&lat=2008&lon=4226&layers=BT If one has the surname Dunbar, and R-S5750 SNP then they adopted the surname as being “de Dunbar” from Dunbar. If one has the surname Cockburn, and R-S5750 SNP then they adopted the surname as being “de Cockburn” from Cockburn, near Dunbar. This is supported because of the closeness of Dunbar, and Cockburn, and sharing from the same Y-DNA grouped region. The Dunbar are dispersed with their concentration, because Dunbar had battles; https://en.wikipedia.org/wiki/Battle_of_Dunbar There were three Battles of Dunbar between England and Scotland. Battle of Dunbar (1296), in the Wars of Scottish Independence Battle of Dunbar (1489), Scottish victory in sea battle Battle of Dunbar (1650), in the Third English Civil War There was not of nearby Cockburn a battle, and that is why the Cockburn are concentrated near Cockburn http://named.publicprofiler.org/ using census data.
Dunbar is noted for; https://en.wikipedia.org/wiki/Battle_of_Dunbar_(1296) https://en.wikipedia.org/wiki/Battle_of_Dunbar_(1650) Battles in 1296, and 1650. The people with the name Dunbar are distributed away from Dunbar. Update on Y-DNA Cockburn project By Bruce Cockburn January 23, 2011 Shows similarity of the Dunbar-Cockburn Y-DNA http://www.genealogy.com/forum/surnames/topics/cockburn/429/ https://www.worldfamilies.net/files/mht_uploads/C_/A738CB41/CopyofDunbarResults03122017a.htmDunbar Y-DNA has similarities with Cockburn Y-DNA. There is coal and fertile land from Dunbar to Cockburn. It is felt that when the surnames were adopted, they came out of a similar Y-DNA base, where the people “de (of) Dunbar” became “Dunbar”, and the people “de (of) Cockburn” became having similar Y-DNA. The “Dunbar” were distributed by battle, and the Cockburn not affected by battle, settled near the locality of Cockburn (a burn with coke/coal). The Cockburn (on 1654 Blaeu map), is not noted for battles like Dunbar is. The Cockburn are distributed still near Cockburn “de Cokeburne”(of coke/coal burn) where on the satellite map there is a burn. “Thus David II (1324-1371) grants Hugoni “de Dunbar” 10 marks sterling de custuma burgi nostri de Aberden and a precept is given to the chamberlain and customers of Aberdeen to pay it annually The same king grants Alexandro “de Cockburne” 20 libras sterlingorum de magna custuma burgi nostri de Hadyngton.” The Scottish Jurist: Being Reports of Cases Decided in the Supreme Courts of Scotland, and in the House of Lords on Appeal from Scotland, Volume 31 T. Constable, 1859 Page 682 Where “de Dunbar” is “of Dunbar” and became the surname “Dunbar”, following “de Cockburne” is “of Cockburn” which became surname “Cockburn”.

Part of the Y-DNA move went to Dunbar, and the other part to the ancient town of Cockburn. They were at first referred to as “de(of) Dunbar”, and “de(of) Cockburn”. When they adopted/acquired their surnames, they took on the surname of the respective community in which they lived. So R-S5750 with the surname Dunbar, their surname originated from living in Dunbar, and it follows that the R-S5750 Cockburn that their surname originated from living in Cockburn. Though Dunbar, is distributed away from this region, for the Dunbar R-S5750, the name can be said to be “de Dunbar”. Given the distribution pattern for the Cockburn, we can go on to say that other Cockburn Y-DNA likely came from Cockburn, especially it is felt if correlation to Dunbar Y-DNA. If correlation of other Y-DNA are found between the Cockburn and Dunbar, then it is likely these people also originated their surnames from the respective communities of Cockburn and Dunbar. It should be noted, was not able to find Cockburn itself, but a mound/hill/law, near Cockburn called Cockburn Law, and a path from Cockburn to then sea, called Cockburnspath.
