Questions: Who are the three children in the story?

Context: 
Chapter 1

There were once three children, called NAME_1, NAME_2 and NAME_3. All their lives they had lived in a town, but now their father had a job in the country, so they were all to move as soon as they possibly could.

‘What fun to be in the country!’ said NAME_1. ‘I shall learn all about animals and birds!’

‘And I shall pick as many flowers as I want to,’ said NAME_2.

They arrived at last at the tiny station where they were to get out. A sleepy-looking porter put their two bags on a trolley, and said he would bring them along later.

Off they all went down the winding country lane, chattering loudly.

‘I wonder if we’ve got a garden?’ said NAME_3.

But before they reached their new home they were tired out and could not bother to say a word more to each other. Their cottage was five miles from the station, and as the children’s father could not afford to do anything but walk there, it seemed a very long way indeed. There was no bus to take them, so the tired children dragged their feet along, wishing for a glass of warm milk and a cosy bed.

At last they got there - and dear me, it was worth all the walk, for the cottage was sweet. Roses hung from the walls - red and
