Answer 1

You can only have one CNAME resource record for a page (both user pages and project pages) defined in the CNAME file in the root of a Git repository.

You can circumvent this by creating a CNAME record for your host(pear) in your DNS settings pointing to florianwolters.github.com, and making a entry in your CNAME file in repository for pear.florianwolters.de
