I sort-of-know a little girl named
Trinity. We attend the same church. She's about 8 years old, I'd say. But beyond that, I don't know about her or her family.
Whether the name has symbolism for her/her parents, I couldn't say...perhaps, since they do attend church! (
Roman Catholic.)
Not a name I would use, though I can't quite fit myself into any of the categories you list. "Too much to be a name", perhaps, but that's just me;I don't strongly dislike it.
And who knows, maybe
1. The family just liked the sound of it. OR
2.Perhaps her parents have insight into the concept of the Holy
Trinity, and want to celebrate, I guess you'd say, that.
