Clans

Just a few days ago I accidentally gave my clan commander over to a new member, and I spent years building this clan up and now this person seems not wanting to give my clan back. All that hard work and time putting this clan together and one stupid click of a button and give the clan commander to a member who don't seem to want to give it back. Is there any way to look up who first put their time and money into the LRRP clan?
