Basques were found to have the highest incidence of Rh negative blood, and Basque people have usually dark hair and dark eyes, no blonde or red. So I think that trait is not usefull trait to identify rh negs.

The Berbers live in the Northern part of Morocco. They have the highest percentage of rhesus negatives.
Berbers are the indigenous peoples of North Africa west of the Nile Valley. They are discontinuously distributed from the Atlantic to the Siwa oasis, in Egypt, and from the Mediterranean to the Niger River. Historically they spoke various Berber languages, which together form a branch of the Afro-Asiatic language family. Today Arabic is spoken almost universally by Berbers, along with Darija, as well as French (in Morocco, Tunisia and Algeria) and some Spanish (in Western Sahara and parts of Morocco), due to European colonisation of the Maghreb. Today most Berber-speaking people live in Morocco, Algeria, Libya, Mali and Niger.
Berbers represent the major ethnic origin in North Africa, although up to perhaps a certain extent interbred with other elements (Arab, Subsaharian, Iberian , Punic…), but only about half of the Moroccan population and a third of the Algerian can be identified nowadays as Berber by speaking a Berber language (see there for estimates). Nevertheless, the culture of many Arabic-speaking ethnic groups in these countries is very similar to that of their Berber neighbours and often language may be the only difference between Berbers and Arabs in the Maghreb. Thus, very high estimates of Berber population might include ethnic groups which no longer speak a Berber language. There are also smaller Berber populations in Libya and Tunisia, though exact statistics are unavailable [2] and very small groups in Egypt and Mauritania. Tuareg Berber spread southwards to Mali, Niger and Burkina Faso. Some 600,000 Tuareg Berbers live in Mali and 400,000 in Niger.[26] Prominent Berber groups include the Kabyles of northern Algeria, who number about 4 million and have kept, to a large degree, their original language and culture; and the Shilha or Chleuh (French, from Arabic Shalh and Shilha ašəlḥi) of south Morocco, numbering about 8 million. Other groups include the Riffians of north Morocco, the Shawiya language of Algeria, and the Tuareg of the Sahara. There are about 2.2 million Berber immigrants in Europe, especially the Riffians and the Kabyles in the Netherlands, Belgium and France.
Only around 800 kilometers from the Atlas mountains where the Berbers originate is where you can find the Basque region.
35 000 years ago the men of southern France and the Basque region hunted the wild bison, wooly rhinocerus, horse, and mammoth where they lived in tepees with the women and not in the painted caves according to popular belief. The women would have gathered wild fruits, seeds, and berries where they brought them back to thier campsite. They probably spent most of thier time in those dark tepees and only occasionaly did they most likely wander out of thier tepees to collect the fruit of the plains. The reason being for this is that after menstruation and child birth, they needed protection from the cold and other weather elements to raise and feed thier children. This is probably where the women, over thousands of years, obtained the recessive genotypes like lighter skin and hazel eyes, although not necessarily the dominate phenotype of the O+ blood factor which they most likely picked up 5-6000 years earlier when they ventured out of Siberia on thier way to northern and southern Europe. It is positively sure that a few of the O rhesus positive women joined the O rhesus negative tribe, but a lot of the women travelling to southern Europe just below the Swiss alps likely still had the O rhesus negative factor while those travelling north of the glaciated Swiss alps likely had the O rhesus positive factor. This may explain why a lot of Spanish and Italians presently have dark hair as opposed to the Germans and French who have lighter complexions and blond or blonde hair.
Ireland and Scotland have large amounts of rhesus negatives and so do the Welsh. So how about the Brits? They are Germans. Saxons.

Many have alleged the Pharaos being descendants of the Irish or Scots and a high rhesus negative ratio being an indicator thereof. Also a lot of parallels between Atlantis and the British Isles have been established.

Are there a few original human tribes which are rhesus negative and their ruling over the earth has been maintained for all this time?
