Greetings from Roana, who's trying to get back into
the habit of doing internal commentary ...

"Per fess azure and argent, a dove rising argent sustaining in its claws a serpent embowed counter-embowed gules."

I'm in agreement with everyone else on the list who's been expressing concern over this piece of armory.  As blazoned, the dove *is* required to be entirely on the azure portion of the field, although the serpent could theoretically be drawn crossing the line of division.  I think there's a small case for the blazon being all right as it is -- unfortunately, the real problem with *blazoning* this design is that it's not a very *heraldic* design to begin with, alas.

2. Fredeburg von Katzenellenbogen – New Name, New Device
"Vert, two bars gemels and in chief a lion passant argent."

Just a small point of grammar - the proper plural of "bar gemel" is "bars gemel" - no terminal 's' on gemel.

That's it - the rest of the letter looks good to me.
