Gothmog

[ninja91]

I know that Gothmog is the lieutenent of the Morgul-host. But, I have also heard from my cousin that Gothmog was also the name of a balrog. That brings up two questions:
1. Was Gothmog (orc) known to have any connection at all to the other Gothmog (balrog) ?
2. Are there possibly more than 1 balrog that existed in the third age besides the one that the Fellowship encountered in Moria?

Thanks!
