R-P311 in my family line

Hello:

I am also R-P311.
My paternal family came to the United States from Sweden.
The farthest I can trace my pure paternal line is back to my great-great-grandfather.
His name was Eric Ström, and he was born in 1758, in Genarp, in Skåne county, Sweden.

I am a 75 year old retired scientist doing genealogy as a retirement hobby.

Robert Strom

My family name is Venable. The Venables came from the Normandy region of France and into England in 1066 with William the Conqueror. My line settled in North Carolina, but were in Pennsylvania (early 1700's) and Virginia before that. Have been unable to connect them to whom they belong in the U.K.

All of these comments on each of our family lines and R-P311 appear to all point in the same direction. Family names came from occupations, locations or family members ( Robert's son = Robertson) Many family lines in UK came from Normandy. Normandy was settled by North men & woman or Norse men & women thus the name Normandy. Could we assume that our common ancestor was from northern Europe, Sweden- Denmark area and a son migrated south to France and the on to the UK?

My wife's paternal line is Anderson with a ydna haplogroup of R-P311. The earliest known ancestor was from Northern Ireland born in the 1830s. Has anyone in this group done the Family Tree DNA test? I believe they have a different name for this haplogroup.
