Dear Ian and List The url I got my info from has long since been "URL not found" most unfortunately. However, a collection of info can be gleaned from the usual well informed sources:- _www.cyndislist.com/names.htm_ (http://www.cyndislist.com/names.htm) _http://www.genuki.org.uk/big/wal_ (http://www.genuki.org.uk/big/wal) These well known general sites will give hot links to pages, some with more in-depth detail than others, onto the naming system we all love. Regards Jude
