How can I know the date of when a character did a name change?

Question

Is there any fansite/tools that tell us when Character with Former Names made a name change? 

Answer 1

Yes there is a fansite where you can check it out. It's TibiaVip. I have marked the place where you can see the date of the name change in red in the screenshot below.

I noticed that not all name changes are visible on this page but maybe this will help you.
