Listening in the hall, Lucy heard her mama suggest that maybe they should go, that maybe they had no choice. She didn’t understand what was meant by that, or what it was that would quieten. She moved closer to the slightly open door because the voices were lower than they had been.
-We have to think of her, Everard.
And in the kitchen Bridget said:
-The Morells have gone from Clashmore.
"I heard." Henry’s slow enunciation reached Lucy in the dog passage, which was what the passage that led from the kitchen to the back door was called. "I heard that all right."
"Past seventy they are now."
Henry said nothing for a moment, then remarked that at times like these the worst was always assumed, the benefit of any doubt going the wrong way in any misfortune there’d be. The Gouvernets had gone from Aglish, he said, the Priors from Ringville, the Swifts, the Boyces. Everywhere, what you heard about was the going.
Does it mean: they are now more than seventy?
I think "they" refer to Morells
