The Rh blood type antigen was first identified in rhesus monkeys.
The 3 blood type antigens important for blood transfusions success are named: A, B, and Rh and result in types: AB+, AB-, A+, A-, B+, B-, O+, and O- in different combinations.
The Rh factor got its name from the Rhesus monkey, as they were first used in research to identify the presence of the protein in blood. This monkey's blood was instrumental in the discovery and understanding of the Rh factor in humans.

The term "RH" stands for Rhesus factor, named after the Rhesus macaque monkey in whose blood the factor was first discovered in 1937. The RH factor refers to a specific protein present on the surface of red blood cells that can affect blood compatibility in transfusions and pregnancy.
The rhesus monkey gave the Rh factor its name. The Rh factor is a protein found on the surface of red blood cells, originally discovered in rhesus monkeys before being identified in humans.

To the second question the answer, in short, is YES; To answer the first question, there are four logical blood types: A, B, AB, and O. Then there is the Rhesus factor: either positive or negative. So there are actually eight types of blood a human can have: one of the above types with a negative Rhesus factor or with a positive Rhesus factor. Rhesus factor is a factor which compares human blood to a Rhesus monkey's blood. A negative result means your blood is not comparable to a Rhesus monkey. Blood types are inherited from your parents. If one parent has type A+, and the other has a B-, your blood type can either come out as A, + or -, or B, + or -, or the rare AB, + or - but not O. While type O negative is the universal donor, type AB positive is a universal recipient.
The red blood cell antigen named after the rhesus monkey is the Rh factor or Rh antigen. It is an important antigen in blood transfusions and plays a role in hemolytic diseases of the newborn when an Rh-negative mother carries an Rh-positive fetus.
I think Rh is not a blood group. Rh stands for a factor and derived its name from factor found in the blood of Rhesus monkey.
It's from the Greek "Rhesos," which was the name of a mythological figure. It's from "Rhesos", king of Thrace in north Greece and an ally of king Priamos in ancient Troy. His name was given to the monkey "rhesus macacus", when the experiments on this breed (of monkey) led to the subdivision of blood (positive, negative).
