I think the server should add some sort of family job that a player could inherit or create for their family members.
Example: The Ollivanders have been known for making wands since 382 BC. Anybody in the Ollivander family should automatically be able to inherit the wand-making business once they're at a year (maybe their 6th or 7th year?) where they're old enough to have a part-time job.
Please get back to me soon if you think allowing this would be a good idea.
