I've just discovered that I have a Holy Roman Empire coat of arms that's over 300 years old.

My father found the description of our family coat of arms in the family archives. Nicolas de Willemin, my ancestor, received an Imperial Diploma of ennoblement in Vienna on February 11, 1692 for his services to the imperial troops. Funny to know that although I'm French, my family comes from the nobility of the Holy Roman German Empire.

Here is the description: Gules, a shield in heart Or, charged with a bend Azure, surmounted by three mullets Argent. On a chief emanated Or and azure.
I am not an english native speaker though. No idea if the translation was correct ?

Here's the french (and original) description just in case : De gueules à l’écu d’or posé en cœur, chargé d’une bande d’azur, surchargé de trois étoiles d’argent. Au chef émanché d’or et d’azur.

I have no idea how my coat of arms would look like. My father couldn't find a drawing, only the description. My family branch is not the one that has kept the money and prestige. So we're a little less informed. ahah

Could someone show me what it might look like? Might tip if it's really good.
