God has not given us one set of leadership principles for marriage relationships, another set for biological family relationships, and yet another for relationships in the larger (church) family. Though each sphere of influence broadens in terms of function and responsibility, the basic leadership principles are the same. A husband is to be a servant-leader to his wife, a father is to be a servant-leader in his family, and elders/overseers are to be servant-leaders in the family of God.
