Holy cow, you weren't kidding this is long.
I'm going to confine myself to listing my favorites. But I really do love almost anything historic. The older the better. :-)
My favorites (if it says thanks, that means it's new to me):
Abel,
Adam,
Adrian,
Angus,
Alan,
Alban,
Algernon,
Aloysius (
Louis),
Amias,
Ambrose,
Archibald,
Arthur,
Aubrey,
Augustine,
Averill,
Balthazar,
Barnabas /
Barnaby,
Deodatus (thanks),
Hercules, (oops, got to go)
By the way, I don't think it's fair to call some of these "creative" spellings. Since spelling wasn't standardized until several centuries later, all of these spellings were acceptable at the time. (I assume by putting quotations around the word creative that you use it pejoratively.)
