To Paradise (clarification needed)

Hi everyone, I am slightly confused about the name of David’s sibling. In page 88, it says Eliza who was the sibling he liked the best. However in page 84 when he talks about his siblings he says John and Eden. And Eliza was the one who left the room when the siblings was to discuss with the father. So is there a typo on page 88 or am I missing something? Could be due to English being my second language, but thanks for the support.
