Well, a name isn't necessarily who they are. Maybe you could ask your god how he would prefer to be honoured.
I'll give it a try. I remember asking once, a long while ago, and I recieved visions of meadows and forest and of forest animals. I'm not sure what that meant.
It's pretty hard crafting your own religion, with deities you're not sure anyone else worships. Believe me, I know
wink You sort of have to follow your instincts, check and re-check, expose yourself to the gods and hope for insights. You have to try things, keep what works and jettison what doesn't. Keep a lot of notes of what you're doing and the impressions you get from it. What hasn't worked before may work in the future if you change the way you do it or the context in which you do it.
Now for me, my God is also related to the sun. I had good experiences with daily devotions at dawn, when I was able to be up to see the sun rise. You may also, or perhaps you won't.
EDIT: you mentioned your goddess was related to a trinity symbol? You may want to track down that symbol's origins, and see if she is a member of the pantheon associated with that symbol.
