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.
Heredity
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.
Thomas Hardy
