I am very happy of knowing of other members of the "family".
In the place I live (Bilbao, in the Basque Country in Spain) it is not an uncommon surname and it is quite easy to track its emblem down.
In fact, my mother has one upon one of her home´s doors!
It is thirteen stars (more or less round ones) in four rows: 3 stars above, three in the middle, another three below, and the last at the bottom. I am not sure of their colour, but I think they´re red.
Maybe there are other variations, but I don´t know of them.
