it's from the surname Latchman.
My favourite book on surnames :) doesn't list Latchman - but it lists Latch, Latchford and Latchmore - in all of these the latch- is from an OE word meaning stream. -man in surnames tends to mean either 'servant' or just 'man'. So best guess for Latchman - 'servant/man who lived by a stream'.
