How did peerage inheritance relate to the House of Lords?

When did Britain restrict a peerage to one family member, and was that connected with the House of Lords?

The connection was partial: noble status carried a Lords seat and usually descended to the eldest son, but no precise origin date is given.

A viewer asks when Britain limited a peerage to one family member and whether the practice was tied to the House of Lords. No neat origin date is given, but noble status carried the right to sit in the Lords and required a recognized claim. In ordinary succession the dignity passed to the eldest son, though deaths and irregular succession could complicate the result. The answer is a limited institutional explanation rather than a complete history of the peerage.
