Help needed on the names of paternal grandparents

I would appreciate anyone who could tell me the names of the paternal grandparents on the baptism record for Jose Braulio Romulo Luna (last entry on the left-hand page).

It looks like Pedro Luna and Guadalupe Bendures to me, but I'm not familiar with Spanish names. The godmother also has the same surname as the child's mother.

This is the only record I've been able to find with the names of these people and I need to know what they are in order to continue tracing the Luna family.

Thank you ...
Denise
