Adding name to GPG Key with Signatures

[pteri498]

I have a GnuPG key that's been signed by several people. I want to add another name (and e-mail) to it.

I used seahorse to do it, but it doesn't look like the old signatures migrated to the new name.

Is this standard behavior? Is there a way that I can migrate the signatures, or do I have to request that the signers themselves do it?

If you use Thunderbird as an email client, it is pretty easy to add signatures. See screen shot
