In England not every family has one-it´s usually only the aristocracy but you can design one if you want to.

Dear Stella, that is correct. Some German, Spanish and  British families are very proud of them.

Spaniards are especailly proud!! Here is one example

We didn´t really get the answer to your original question though !

Yes, I am still waiting....................

Here is more about the Mexican flag, i.e. coat of arms:

The Mexican Coat of Arms depicts the founding of Tenochtitlan, the Aztec capital. The Aztec god, Huitzilopochtli, told the nomadic tribe that they should settle where they found an eagle devouring a snake, perched on a cactus, growing from a rock in the middle of a lake.

Yes - is this going to be a discussion of coats of arms in general?  Because if it is I will move it to the General/Off Topic forum.

Go ahead Jill, that is fine with me!! Thanks.

This was never approved by Turkey. (1925)

I like ones with rampant lions. I believe there are special names for the colours used in heraldry too.

 And register it or something,yes?

There´s a great site to design your own coat of arms on google. ( Vand A-design a coat of arms.)
