Mexican Sir Names

I am playing a guessing game with a friend: I need to guess her last name.

Her exact wording was "possibly" when I asked if the name was of Mexican decent. She then said that it starts with G and is followed by 6 letters.

Google has failed me horribly, any ideas?

Gonzales?
Gutierres?
Gallardo?

Gerrero?

*Surnames.

I saw all of those... apparently I cannot count in sets of 3, I thought they all had 8 total letters.

Guerrero?

Fixed.

Garcia?

Really, most (if not all) of the surnames in Mexico are Spanish, not Mexican.

Galeano?

Martinez
Chavez

etc.

Guillermo? Not six but eh

Gallego?

ugh... every time i see this thread im reminded of my earlier post:

*Surnames.

Fixed.

Garcia?

It doesn't always have a u.

Galaviz
Galicia
Galindo
Garibay
Guevara
Gurrola

It doesn't always have a u.

I'm 99% sure it's a typo without a U ( I mean, even if someone was actually called Gerrero, it's a typo of Guerrero, because they even have different pronunciations)
