My ancestors came to Scotland from the Garfagnana area of north-west Tuscany which has a 76 pc incidence of haplogroup R1b, the same haplogroup that prevails in Scotland and Ireland.
Phenotypically, few Garfagnini look Scots or Irish and possible different subclades of R1b cannot account for these phenotypical differences.

Question: Who looks more similar, Rib3 Northern Iberians and Irish or non R1b3 southern Italians and Irish?

I'm not saying that being in the same haplogroup means you look the same, or even similar, but statistically it makes a contribution to appearance.
