Could he have had a brother, killed in Rome by Nero?

The "brothers" of Jesus were James, Joses, Judas, and Simon.
None of which are on record as traveling to Rome.

Eventually James assumed leadership of the Christian community in Jerusalem.
As friction between Jews and Christians increased, the Christian tolerant procurator, Festus, died ~62CE.
Before Nero could send a new procurator, the priest Annas (the younger) had James thrown from the temple walls and his body stoned.
