I've no idea what the name Ashlie means - I've always assumed my parents wanted to name me in a hurry, so arranged a spelling that meant they wouldn't have to wait for the boy/girl question to be answered. (trad. boy spelling - Ashley, trad. girl spelling - Ashleigh. As a girl, I like my spelling better!)
As for my surname...I'm hoping that one of my ancestors was very tall and just got the name "Large" hung on him...in a manner of speaking. Does anyone have a better suggestion?
