For the Boil/Dust Releases being part of the Mizukage's/Muu's Clan. Yes, they must've had a common ancestor, but it does not mean the KG is exclusive to a certain Clan, same with how you chose to use your KG. Also sources for where it is stated where Muu/The Mizukage are even part of a Clan. Being part of a family (Being "Clanless") is pretty common as seen with most Background characters who do not display any noticeable trace.

Clan or Family, it's the same point. It's exclusive to them. For example, the Yuki Clan(who are known for their Ice Style KG) are pretty much no longer a clan anymore due to the persecutions of the Land of Water forcing them into separation and hiding. Haku is a descendant of that clan. If he were to have started a family, then the Ice Style would still be exclusive to their blood since they're descendants of the Ice Style-using Yuki Clan. I hope I was making that clear.
