Genetic genealogy has in many cases answered a lot of questions and other times it has provoked new ones. Angela Lewis, who in my opinion is the most knowledgeable and lead authority on Gurulé genealogy has opened up a question as to whether or not the Gurulé progenitor, Santiago Gurulé and his wife Elena Gallegos had any legitimate male children. This leads to question, are contemporary Gurulé families truly carrying on the bloodline of Santiago Gurulé? The answer to this question is being investigated using genetic genealogy via testing living male descendants that carry the Gurulé surname. Currently the results for Gurulé samples are resulting into three distinct Haplogroups.
Haplogroup I1 (I-M253): Nordic (Northwestern European origin)
- This group appears to be matching various surnames.
Haplogroup Q & Q1a3a: Native-American origin
Haplogroup R1b1: Western European origin
- This group appears to be matching Martin Serrano Y-DNA sequence
The most prominent of the three groups is Haplogroup I1 (I-M253) with nine individuals with the Gurule surname matching this Y-DNA sequence. This Y-DNA sequence is also matching a slew of folks carrying various surnames and some of these surnames have multiple folks with the same surname matching. Some of the results with multiple surname matches in frequency are Espinosa (2), Martinez (3), Sanchez (2), Santistevan (2), Gallegos (2), and Garcia (7) just to name a few.
In genetic genealogy, the sharing of genealogies is critical for the validation of a given lineage because it allows for lineage comparison by mapping out the trail of those tested to their common paternal ancestor. In this case, without genealogical comparisons, an argument could be made that the Y-DNA sequence in question could be the progenitor lineage of any of the surnames mentioned above. Just because one surname has numerous matches does not tell us much. In such a case, without a genealogical comparison for those tested we do not know how many generations back they share a common ancestor. Knowing the common ancestor is a crucial data point for validating to a given point in time.
Taking this approach we have mapped out seven of the nine male Gurulés all tracing back to Antonio Gurulé, each with unique paper trails. The comparison between these lineages has proven the Y-DNA of Antonio Gurulé who was born 1703 and was a supposed son of Santiago Gurulé and Elena Gallegos. Although the true parentage of Antonio is in question, the seven male Gurulés matching can say without a doubt that they truly are direct male descendants of Antonio Gurulé and his wife and Antonia Quintana.
