Norris has several to chose from.

I like this one because of the leopards.

This version of the family coat of arms is a little flowery for my taste and bears only the "newer" family motto "In Ardua Petit" (sometimes "In Ardua Tendit"). That translates as "He has attempted difficult things" or "He reaches toward things difficult of attainment", which seems fitting for a collector.

The original family motto was "Deus Refugium Nostrum" which translates to "O God, our refuge" from Psalm 45 and part of the Prayers after Low Mass.

When it comes to the family coat of arms, I much prefer the version below (in the top right corner), which is the one I grew up with and contains both mottos. Apart from this image, though, I cannot find a good graphic of it on the web. I'll have to get mom and dad to send me a scan.
