I admit was surprised when I checked the SSA list. I guess I thought of
Garrett as a very modern name. I've only met one, and he was born in the late 80s, so I'm sure that affected my perception. It has a longer history and more staying power, I think, than I gave it credit for.
It's awesome that you can trace the history of the name within your family the way that you can. Thank you for your comments.
