Hi Colin This is not much help to you, but I'd just like to point out that when you say "David Ogilvy who did his apprenticeship at the Signet Law Firm Edinburgh" you are mixing things up a little. There is no such thing as "the Signet law Firm". However, a number of solicitors (not all) are Writers to the Signet (WS for short). This is a kind of superior grade of solicitor (or "writer" which is the older Scottish term) although its superiority is at least as much in terms of simple prestige as it is in practical value. Some law firms, whose partners are Writers to the Signet, put "WS" after the name of the firm, eg Brown and Smith WS. I suspect your David Ogilvy did his apprenticeship in one such firm and may well have become a Writer to the Signet himself. (An apprentice, by the way, is the Scottish term for what the English would cal an articled clerk.) There is perhaps one other possibility as regards a particular firm. At the moment, the firm of Dundas and Wilson are Clerks to the Signet (ie clerks to the Society of Writers to the Signet) and they are called Dundas and Wilson CS. I don't know whether it would have been the same firm in the days of your David Ogilvy, but that might have been a firm which could be called "THE Signet law firm". You can find the Signet Library at http://www.signetlibrary.co.uk/ which might be of some help. Hope I haven't just confused you further. Cheers Alan
