Iberian J-M241 Lineages

A number of J-M241 lineages are found in the Azores. Many Azoreans are enthusiastic genetic genealogists.

Several subclades of J-M241 are found in men living in Iberia or who trace their male line to Iberia.

As in all of my articles, all most common ancestor dates mentioned come from YFull estimates.

Z600(xZ585,YP157) is found in the Dominican Republic. Not enough distant matches have been found to establish how long their ancestors may have been living in Iberia.


Moving down the YFull tree we see a seemingly exclusively Iberian subclade of FGC64029 called Y95770. This branch is defined by a Brazilian and Columbian whose most recent common ancestor lived about 2000 years ago, however their ancestors did not migrate from Iberia to South America.

Neither of these men have close male line matches, however their family history, surnames and closest autosomal and Y matches indicates that their lineages represent two separate migrations from Lebanon to South America. If some of their closer Lebanese matches get on the YFull tree they will likely be in the same subclade, which will make it more obvious that this is in fact a Lebanese origin subclade.

It's important to keep in mind that even if FGC64029 was living in the Levant, that its ancestor from 1200 BC, Y146400, also sired an Albanian lineage. Since there is no diversity in the Levant upstream in L283 but there is in Europe, the likely origin of Y146400 is Europe. Sometime between 1200 BC and the first century BC their ancestors migrated to the Levant.


Next in the tree, CTS6190 appears to have either been born in Iberia or spent the bulk of his life there, having sired 3/5 lineages with Iberian presence, some solely found in Iberia. I wrote about this lineage here.


Next we have newly discovered Y161916 formed by a Spaniard and an Albanian whose most common ancestor lived 1100 BC. Because this lineage has an Albanian and its sibling Y20899 consists of almost exclusively Albanians, Italians (who may turn out to be later colonists from the Western Balkans) and those of the West Balkans, the ancestor Z38300 likely was living in the West Balkans or Adriatic coasts in 1300 BC. It is interesting to note that these TMRCAs occur during the Bronze Age Collapse. So these mens' ancestors likely proliferated at this time because they were lucky enough to survive and have offspring in a time when many other lineages went extinct. They do not seem to represent a powerful, multi-generational dynasty because the number of children in each branch is low and there are no successive subclades.


Next we have Y32373 below Y21878. This one is a riddle because it is formed by a Russian and Spanish/Portuguese men whose most recent common ancestor lived 800 BC. The Spanish and Portuguese have a most recent common ancestor who may have lived from 500-1000 years ago, roughly estimating from STR genetic distance.

The sibling of this branch is CTS11100, consisting of the descendants of a prolific man who lived 1600 BC. His descendants now live scattered between the Balkans, Central Europe, Scandinavia and both sides of the English Channel. Both of these sibling lineages require additional, less widely distributed subclades to be discovered before a reliable migration theory can be formulated.


Next we have Y87605, a subclade below prolific Z631. Until today this branch was known to consist of just two men, one tracing descent to Bedford, England in the 18th Century and one to Cariñena, Spain in the 17th Century. Their most recent common ancestor lived 400 BC.

Y87605 may have been living in Iberia for over 1000 years, due to the high STR divergence of these three men.

Today I found two other Iberian men (one from Spain and one from Portugal) who are distantly related to this Spanish Y87605. Using STR Match Finder I was able to discover that these men are very likely to be related on the basis of sharing 6 rare STR marker values (see above), even though they don't show up as FTDNA matches. Further testing may reveal that these men descend from an ancestor who may have been living in Iberian over 1000 years ago.


There are two Iberian subclades of J-M241 under Z1043. Y154639 is below Y26712 and consists of an Azorean and a man descending from French Huguenots he believes were from Bern. I may have found a connection between the Azorean and a Brazilian man but it is not as clear of an STR match as the above.


The other Z1043 branch in Iberia is CTS11760 which has two subclades found in Spain. I have theorized here that these men may represent the offspring of Celts who migrated extensively throughout Europe in pre-Roman times.


The final Iberian group is found on the Azores and we have only recently received the results from this Dante Labs order placed during the Black Friday sale of 2018 (10 months ago). I correctly predicted that they may be the first European Z2432 yet found given their closer STR match to men in Z2433 and shared rare STR alleles.

All we know so far is that this lineage descends from Z8326 which most likely was living in India 4400 BC. Where they were living between then and their arrival in the Azores is still a mystery.

These posts are the opinion of Hunter Provyn, a haplogroup researcher in J-M241 and J-M102.

  1. there is a Iberian marker that is not referenced yet here and that there is a good number of iberian people under it j1- cts 5332
