# Creating a Lineage

After opening your TOY, you can give your newborn PETS a custom **Family Name** and create your **Raregotchi Lineage**.

Each Family Name must be unique and can't be repeated. If the name you picked is already taken, you will have to choose another one.

The name will be registered in the NFT's Metadata, so once you have chosen your **Family Name** you won’t be able to modify it.

As a TOY owner, you can choose whatever Family Name you want. However, all names will be manually reviewed by the Raregotchi team. Any offensive, copyright-protected, or inappropriate words will be automatically rejected.

We recommend checking our Community Rules in [Discord](http://discord.gg/raregotchi) as a general guideline for name picking.

**Quick Note:** Choose the coolest or the funniest name you can think of. But be respectful!
