Oh, one more tip-- If you decide to go the route I did, and register your heraldry with the SCA, here's the submission information:
Maryland and Virginia are in the kingdom of Atlantia. Heraldry submissions are through the local kingdom. Submission fee is $10 per element (persona name must be registered with or in advance of your device), so if this is your first time registering anything, name and device together are $20.
http://herald.atlantia.sca.org/success.htmI thought you need to be a paying member, but I don't see them mentioning that anywhere. It might be possible to just register the arms without actually signing up.
Forms are here:
http://herald.atlantia.sca.org/forms.htmIdeally it's good to consult with a herald in the SCA first, since they want documentation of authenticity, which they can provide on your behalf. I did mine at Pennsic at the herald's tent. They had tables covered with books, and you can just flip through it for period names and the like. My arms were already painted on my shield, and I just brought a print-out of it, so that part was easy (and thankfully they didn't ask for changes), though they spent more than an hour looking through prior registrations for potential conflicts.
