I was Captain on Aircraft X; ZZZ to ZZZ1 today.  A large family traveling together with some adolescent children created a disturbance at the gate area and continued after boarding.  The station CSM [Customer Service Manager] tried to help contain their behavior; however; after my FA asked one of the children to wear their mask properly once boarded; the family took exception and caused a stir using unacceptable language.  I stepped back to salvage the situation and calm the passengers; but I was not successful; and I asked for several of them to deplane.  Local security and both station managers and in flight managers arrived to assist.  Good work by the local ZZZ CSM allowed us to only remove the X adults and the several children.  This resulted in a delay; of which we made up some enroute.  Flight was uneventful otherwise and several passengers stated appreciation for our handling of the situation.CSM attempted to preempt any problems prior to boarding.  She was a great CSM.
Air carrier Captain reported a family was removed from a flight during boarding due non compliance with face mask policy.
