Band of Relatives

Exactly What It Says on the Tin: This is a band trope: Members of a band are related to each other (though it doesn't have to be all of them).

There are two types:
 * Type 1: Some of the members happen to be related
 * Type 2: The Family Band: everyone in the band is related—which is quite common.

Common deviations from this formula include
 * A relative replaces a former band member
 * Two members are related, but one leaves the band
 * Two members are married—but divorce
