My question is why, if the maximum variation is 14 min 13 seconds, has the astro website I have been using to tell me the time of meridian passage been telling me LAN is 12:19 here in Portsmouth?
What's the problem? If your latitude is is 76.3 degrees W, it's .13 degrees past the mid-point of the time-zone, which adds 5.2 minutes to the LAN at 75 degrees W, and since the Sun is 14 minutes late, that's 19.2 minutes after 12:00, which works out exactly as you'd expect.
