As good a guess as any...I think the DNA will eventually reveal all though.
BTW, my dad's Y-chromosome DNA is R1b as are 90% of the Irish and 68% of all other Europeans. It is the most widespread male DNA in all of Europe. The most widespread mtDNA (female) in Europe is haplogroup 'H' (Helena), same as my son's mother. He has the most common European DNA in the family, 'R1b' from me and 'H' from his mother.
I had my DNA tested through the National Geographic Genographic Project and they're constantly doing on-line updates on my DNA lineages. It's exciting.
