Question

What does the phrase “being of the most intolerant brood that ever lived” mean?

Answer 1

The truth was, that the little Puritans, being of the most intolerant brood that ever lived, had got a vague idea of something outlandish, unearthly, or at variance with ordinary fashions, in the mother and child, and therefore scorned them in their hearts, and not unfrequently reviled them with their tongues.
