We do have Hippolytus, Eusebius and Irenaeus writing a little differently. And, we have the evidence of the traditions of the various Christian settlement, such as the ones in India who trace back to (doubting) Thomas and Bartholomew. There weren't any Jews in India at the time.
All three sources put Peter and Paul in Rome.

If there weren't any Jews there, Thomas violated the command of Jesus...
