Is Tom Rosenthal Jewish

Answer 1

MLB player, Trevor Rosenthal, is a devout Christian, so is his wife.

He publicly puts Christian in his Twitter account.

German surnames with 'berg', 'rosen', 'thal', etc are often common among German/Swedish/Germanic people, not just among Jews who adopted Germanic last names

Answer 2

Tom's father is of mostly or entirely Jewish background. Tom's mother is not Jewish.

Tom was not raised in the Jewish religion, although he acknowledges his background.
