Eleven of the twenty-two Álvarez members that have been tested have come out Haplogroup R1b1.

Álvarez - 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.

Two of the twenty-two Álvarez members that have been tested have come out Haplogroup J1.

Álvarez - J1: Semitic Origin. Haplogroup J is 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.

Two of the twenty-two Álvarez members that have been tested have come out Haplogroup J2.

Álvarez - 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.

Two of the twenty-two Álvarez members that have been tested have come out Haplogroup G2.
 
Álvarez - G2: Caucasus of Europe. This is a fairly rare haplogroup found mostly in men from the Mediterranean, the Caucasus, and the Middle East. The highest concentration of Haplogroup G men is found today in the Caucasus Mountains, in several small states to the south of Russia, and in Georgia, Armenia, and Azerbaijan. The G2 branch of this lineage (containing the P15 mutation) is found most often in Europe and the Middle East. The Alan Sarmatians were military allies of the Vandals and the Suebi during the conquest of Iberia, it is likely this is the origin of haplogroup G2 in Spain. The Alan Sarmatians' ancient homeland was the Caucasus Mountains. About 8% of northern Spaniards share this origin.

Two of the twenty-two Álvarez members that have been tested have come out Haplogroup O.

Álvarez - O: East Asian origin. This lineage dates to about 35,000 years ago when it evolved in Central or East Asia. Over 80% of today's East Asian population is haplogroup O, and this lineage is nearly completely restricted to East Asian populations.

The twentieth Álvarez member that has been tested has come out Haplogroup I.

Álvarez - 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 twenty-first Álvarez member that has been tested has come out Haplogroup E1b1b.

Álvarez - 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 twenty-second Álvarez member that has been tested has come out Haplogroup Q.

Álvarez - 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.

The twenty-two Álvarez members did not match one another. From this one can conclude that there are more then one genetic line of Álvarez'.
