Wuthering Heights: Family Tree

"The intruder was Mrs. Heathcliff."

This is the biggest jumble of names and relationships of my LIFE! How the heck is the average human mind supposed to keep these in check? They can't. So I made  my own family tree. Thank me later.
Mr. and Mrs. Earnshaw                   Mr. and Mrs. Linton
                  I                                                     I
Frances=Hindley-Catherine=Edgar Linton-Isabella Linton=Heathcliff
             I                            I                                            I
   Hareton Earnshaw = Catherine Linton    =  Linton Heathcliff

Weirdest thing of my entire life.
