During the 1981 hunger strike, did IRA leaders intimidate the strikers by threatening to harm their families?

Answer 1

The song they sang at Bobby Sand's funeral was "He Ain't Heavy, He's My Brother."

No they were not threatened.

Answer 2

Its actually impossiblle to say with any certainty. Quite possibly, although it is unlikely that any threats came directly from the leadership of Sein Fein, who had too much to lose in terms of political credibility. Obviously, once dead the hunger strikers became the martyrs they were intended to be.
