Well, it looks as if we are definitely looking for different Granahans. I had heard that there were two distinct Granahan families - one with predominately fair skin and reddish hair, the other one with darker features. I come from the one with fair skin and reddish hair, although my hair is blonde. My Dad had a very red beard when he grew it.
If you want, I can send you pictures of my family members because I have found that comparing photos is often the best way to determine if we are connected.
My email addy is firstname.lastname@example.org
and I hope we can keep in touch.
