After 3 days of reading about the birthmark I suddenly remembered my younger brother Jim Perkins has the same thing. I called him to tell him about others apparently having the same mark. Jim's birthmark is at the hairline and is not discernible unless he gets a very short cut. I asked him to contact his children and ask them if they have the same thing. I find this very interesting. We are descended from Perkins in Goochland Co Va, Caswell Co NC, Green and Hart Co Ky, Floyd and Harrison Co Indiana. Wanda Perkins Stepp
