Wedding God parents

This might seem like a odd question and a lot of you would agree that if I don’t want to do then I shouldn’t. But it’s the only request my mom asked from my grandma and grandpa who passed away so I’m going to do it.


My Other Half isn’t Filipino and doesn’t understand the whole Filipino traditions of the coin and candle so we are skipping it.
but we are going to be asking for sponsors. Or god parents. Probably 3-4 different couples actually.
but how do I ask?
should I gift them and just say will you be my godparents? I know my aunties on my side will know what to do but not all my sponsors will understand exactly the kind of honor it is that I’m asking. How do I explain to them that or ask??
