Personally, I'd study the tradition and culture she comes from and approach her in a way that is specific to her worship. Whenever you go to a god, goddess, spirit, etc, in a tradition/culture that isn't theirs, you may find that the version of them you get is vastly different from their traditional worshipers.
You may also get a very, very negative reaction from that being, as you've insulted them. By approaching them from your own tradition/culture rather than theirs, you are saying your way of doing things is better (more right, more real, etc) than theirs. It's condescending, it's insulting, and it's ignorant.
For some groups, like chaos magic, doing so is acceptable as the gods are more tools than someone you have a relationship with. However if you intend to approach them in order to start a relationship, you are better off learning about them; rather than asking them to fit to your perception of the world. Plus it gives you a better face in their eyes; you're actually stepping out of your comfort zone to do something for them.
