The genetic part is kind of interesting--and seems to support the notion that we are all only six degrees of separation away from knowing or being related to everyone currently alive on the planet.

I am told by relatives that not only are there cousins of practically every colour, but many look like family architypes [of which I am one]. I know I have cousins in Brazil who look much like me except for having very dark skin, American cousins who are part Hispanic, cousins who are part Cree, some who are part Chinese [Hong Kong] and some who never left Scotland. The few photos I have seen are quite remarkable--I would recognise some of them were I to meet them at an airport [communication in English might be a problem!]. With any luck, I shall get to meet some of these people someday. Regardless, many of these distant cousins are aware of their heritage, and some of them have surnames to remind them.
