Ans: Your newly approved H1 Visa comes with a new I-94 at the end of its approval page. Check it out.
Assuming that your family is seeking H4 visa stamping, they should use your newly approved H1 extension and get their H4 visa approved.

Ans: Who told you that someone needs to travel to US for stamping? In fact one MUST TRAVEL OUT of US to get any stamping done(No one stamps a visa INSIDE United States)
