Thanks to the what we have learned from testing, both modern testers and ancient remains, it appears that the ancestor of this haplogroup may have originated in western Asia at some point during the Middle Bronze Age, possibly around the eastern Turkey/Armenia/northern Iran area.  At some unknown point, the R-FGC14628 lineage or an earlier ancestor entered the Jewish population.  By the early Middle Ages however, a descendant of this ancestor had migrated into Western Europe.  R-FGC14628 testers appear to have an Iberian connection although we cannot say for certain that Iberia was the origin of the Western European lineage. 

The most numerous descendant branch of the R-FGC14628 haplogroup is R-FGC14600, which is made up by primarily of men of Ashkenazic Jewish descent.  The founder of this branch was most likely a man who lived in the Rhineland area in late 14th century, possibly in Speyer, Germany.  It appears that a parallel Ashkenazic lineage was found in 14th century Erfurt, although it is not known when the two lineages shared a common ancestor.
