Question: is t'pol related to spock?
Answer: JiNX-01 Admiral Admiral T'Pol gives Archer an English translation of The Teachings of Surak, written by Skon in The Catwalk. Also in that episode, we learn that Solkar was the first Vulcan ambassador to Earth. As for T'Pau, she's not part of Spock's family; she just presided over his wedding to T'Pring.
