I see the likeness, Nellie. One day, as I was coming downstairs, I glanced at a picture of my dad as a child and suddenly saw my second GS, although dad was dark haired and brown eyed, and GS is blue eyed and fair-ish. My father's cousin once remarked that as I got out of the car, he could see my mother but by the time I got to the door of his house, he could see my father! Here's Hardy on the subject.
I am the family face; Flesh perishes, I live on, Projecting trait and trace Through time to times anon, And leaping from place to place Over oblivion.
The years-heired feature that can In curve and voice and eye Despise the human span Of durance -- that is I; The eternal thing in man, That heeds no call to die.
