A Family Tree of Sorts

So I'm not sure about the others but I was quite confused at the beginning with the mention of the Catherines and all the people at Wuthering Heights who are related in many, confusing ways. When Nelly Dean, the housekeeper at Thrushcross Grange - Lockwoods's current home, spells out the family history and all the relationships between the characters, I decided I would take this chance to make a sort of family tree (the information is gathered from both from what Nelly tells Lockwood throughout the book and the diary entry that Lockwood read earlier).
