I wish I could do something similar. I have never seen a picture of my grandfather who died young in 1939, but a relative who knew him says I look very similar.
More to the point and in keeping with the spirit of the thread, my sixth cousin, who I made contact with earlier this year tells me that certain facial features in his side of the family are also found in my side of the family. Considering how many generations we have to go back to a common ancestor, that is quite remarkable. I suppose that in a sample size of (say) 30 people, a feature shared by 5 or 6 could well be shared by a similar proportion in another branch of the family, even over such a long period of time.
