Charlie might be the one who is always looking out for the less fortunate in the village. He could help his family bake cookies for the neighbors and go caroling with his friends. His name gives a sense of warmth and kindness, which are associated with the Christmas spirit.
One possible name could be Timmy. It's a simple and friendly name that would fit well in a Christmas story. For example, in a story about a family's Christmas, Timmy could be the little brother who is excited about Santa coming and leaves cookies out for him.
