I have to check with my wife -- one or the other of us are (also?) Grants, as I recall. But it's been a long time and I could be wrong...
I am half Spanish Italian (dad's side) and I only found out very recently about the link to clan Grant. It seems that my great x4? grandpa on my mom's side was a Grant. Now I know where my love of all things Scottish comes from. Researching family history can be so much fun. :-)
Btw, do you actually play the bagpipes? Your screen name suggests that you know something about them...
