All, Please note that the shape of the head is a genetically determined trait with equal contribution from both parents. Although one might expect people to choose mates who are physically similar to themselves, the fact is that the shape of the head (long vs short, front-to-back) is very difficult to see on someone wearing long hair and a hat / cap / bonnet. In other words, any "pattern" you might see among your close Carpenter relatives is purely accidental and transient. John Chandler
