Two questions:
WDYTO Athena nn Thea? I know there isn't exactly a direct link between the two, but I have a special association with the name Athena, though I wouldn't want to actually call a daughter that all the time. I hadn't really considered it as a possibility until I came across Thea and loved it as a nn, but didn't think it could stand on its own. So, would the nn be too confusing since it doesn't come directly from the fn, or does it still work out okay?
Second, WDYTO using Austen for a girl as a way of honoring Jane Austen? (Austen would be a mn only, never a fn)
