Sonia
"Manic the Hedgehog is a green anthropomorphic hedgehog from the Sonic Underground animated series. He is the brother of Sonic the Hedgehog and Sonia the Hedgehog, as well the son of Queen Aleena." So basically, Sonic's brother is Manic the Hedgehog, and Sonia the Hedgehog is Sonic's sister.
Yes he was the voice for all three hedgehogs (Sonic, Sonia, and manic) in Sonic Underground, also the voice for Sonic in Adventures of Sonic the Hedgehog and Sonic SatAM.

He has a brother named Manic the Hedgehog and a sister named Sonia the Hedgehog.
The last answer was not that helpful. Sonic and/or Silver the Hedgehog are not related. In the show, Sonic Underground, Sonic's had only 1 brother and only 1 sister. His brother was Manic and his sister was Sonia. Sonic does not have any more siblings. Silver is just a hedgehog from the future, not Sonic's brother.
