This issue came up for me when I went to visit my daughter who was living in Edinburgh.
We are Scottish on my mother's side and English on my dad's. We have living relatives on his side all over England, but all my mom's rellies (that we know of) are in North America. This has meant that we have known more about our English roots than our Scottish ones.
However, when we were in Scotland, I got to talking with this fella in a pub and when I told him her maiden name, he gave me this long history of that clan. It was interesting and it hit home to me that hey, I am Scottish, too. Actually, we are the dreaded Picts
I didn't immediately break out in a bad brogue and run out to buy our tartan and I'm not even interested in the geneology aspect of it, but for the first time, I related to that part of my heritage.
So, for those of who who are somewhat removed from your heritage, how much do you relate to it?
