This paper must be taken with caution; its goal is to check relatedness of surnames and Y-DNA, so they are not getting regional DNA samples; by that they are getting samples even from Latin America with Catalan surnames, of course they do the same in other Catalan-speaking regions (Valencia, Majorca)... so all DNA is blended. Moreover from 52 surnames three are from migrants (Gasco, Danes...) and 7 are supposedly of Arab origin: more care with such biased data (!).
As to get "ancient" results as to figure out how was late Roman Catalonia i got the results from Old Catalonia (the historical Christian counties, as to distinguish it from New Catalonia, the conquered Muslim lands of Lleida / Tarragona around 1100-1150), excluding also Barcelona by being a city which attracts immigration. Also biased data are keept out (foreign origin surnames as[FONT=Times New Roman, serif] Salom, Gasull, Massot, Melis, Moragues, Nàcher, Maymó, Alemany, Danés, Guasch).[/FONT][FONT=Times New Roman, serif] [/FONT]Doing so the "new" DNA carried by Arabs, Berbers, and Catalan/Frankish Christians in New Catalonia are mainly keept out.
