Hi Jo,
Before spending any money, you might want to read this link first -
http://www.iau.org/public/buying_star_names/
Though it is nice to be able to give a gift to someone you care for,
the reality is that the star naming registries are simply scams.
May I suggest some other gift, such as some warm outdoor clothing?
Others on the forum may also have some suggestions for a thoughtful gift.
