Five of the Eighteen Cervantes members that have been tested have come out Haplogroup R1b1. 

Cervantes - R1b1: Western European Origin. This lineage is also the haplogroup containing the Atlantic modal haplotype. Basque and Celtic people belong to this Haplogroup and they were among the earliest settlers of Spain. 68% of modern day Spaniards share this origin. The following markers are common to the people bordering Europe's Atlantic within a couple of steps; DYS19 (DYS394)=14, DYS388=12, DYS390=24, DYS391=11, DYS392=13 and DYS393=13.

Six of the Eighteen Cervantes members that have been tested have come out Haplogroup Q1a3a.

Cervantes - Q1a3a: Native-American Origin. This lineage is strictly associated with Native-American populations. This haplogroup is defined by the presence of the M3 mutation (also known as SY103). This mutation occurred on the Q lineage 8-12 thousand years ago as the migration into the Americas was underway. There is some debate as to on which side of the Bering Strait this mutation occurred, but it definitely happened in the ancestors of the Native-American peoples.

Two of the Eighteen Cervantes members that have been tested have come out Haplogroup Q.

Cervantes - Q: Native-American Origin. The Q lineage is the lineage that links Asia and the Americas. This lineage is found in North and Central Asian populations as well as native Americans. This lineage is believed to have originated in Central Asia and migrated through the Altai/Baikal region of northern Eurasia into the Americas.

Two of the Eighteen Cervantes members that have been tested have come out Haplogroup J2.

Cervantes - J2: Semitic Origin. Mostly found in the Middle East, Mediterranean, and North Africa. This haplogroup contains the Cohen modal lineage which is found in about 5% of those with this origin. Sephardic Jews and Arab Moors belong to this Haplogroup and they were among the earliest settlers of Spain. About 28% of Sephardic Jews have this origin. 3% of modern day Spaniards have J, J1, or J2 origin.

The Sixteenth Cervantes member that has been tested has come out Haplogroup I. 

Cervantes - I: Nordic (Northwestern European) Origin. In 409 AD, the Suebi (a Baltic people) and the Vandals (an Eastern Germanic people) established themselves on the Iberian Peninsula. Less than 100 years later the Visigoths (an Eastern Germanic people) conquered Iberia, after they had conquered Rome, and settled there in the year 507 AD. The Visigoths? ancient homeland was Sweden, which they had left around Christ's time. These three Nordic peoples brought Haplogroup I and sub-haplogroups I1 and I2 into Iberia. 13% of modern day Spaniards share this origin. 

The Seventeenth Cervantes member that has been tested has come out Haplogroup E1b1b. 

Cervantes - E1b1b: Mediterranean Origin. Mostly found in the Mediterranean, Southern Europe, the Middle East, North, West, and East Africa. The Phoenicians, the Greeks, and the Romans belong to this Haplogroup and they were among the earliest settlers of Spain. 10% of modern day Spaniards share this origin.

The Eighteenth Cervantes member that has been tested has come out Haplogroup N.

Cervantes - N1c: Northeastern European Origin. Haplogroup N1c is a subclade of Haplogourp N, and is perhaps 14,000 years old. Its first appearance is either in Eastern Europe or in Siberia; the question of its exact origin is still not solved. The presence of N1c and N1b in modern Siberian and Asian populations is considered to reflect an ancient substratum, possibly speaking Uralic/Finno-Ugric languages. The Magyars, a group of nomadic people, attacked from the east, from what is now Hungry. Superb horsemen, the Magyars swept across the plains of the Danube River and invaded western Europe in the late 800's. They are probably the origin of Haplogroup N in Iberia.

The Eighteen Cervantes members did not match one another. From this one can conclude that there are more then one genetic line of Cervantes' in the New World.
