Who is The Percivals from Belinda and what is their importance?

The Percivals represent the perfect family who Belinda goes to stay with after arguing with Lady Delacour. They have a loving mother and wife, Lady Anne, a respectable father and husband, Henry Percival, who loves and appreciates them, and intelligent, enthusiastic and loving children. The family enjoy each other's company and are blissfully happy together. They challenge each other with intelligent conversation and a healthy interest in the world, but do not encourage wit for the sake of flattery, gossip or scandal. When both Mr. Hervey and later Belinda meet the family, they are overwhelmed by the difference between staying with them and staying with Lady Delacour.
