A question for Latina Brides

Do the grandparents usually walk down in the processional before the bridal party?

i think its customary that if you the abuelos are still alive--they are seated first, followed by the MOB/MOG and then the BP starts.

if either of our GP's had been alive, i would have had them walk down first.

I don't know what is customary, but I will be asking my grandma to walk down the aisle - she would go first, then mothers of the bride and groom, then the bridal party.
