In conversations concerning the resurrection, the fact that the apostles were willing to die for their belief is usually brought up. Now, you don’t need to defend the validity of every apostle’s martyrdom. In fact, I would just stick with Paul, Peter, Jame, and early church persecution in general. However, Sean McDowell explains some lines of evidence for the historical case of Thomas’ martyrdom in India. Pretty interesting.
