Who is Homer Wells from The Cider House Rules and what is their importance?

Homer Wells is one of the orphans at St. Cloud's. Even when Homer goes to an adoptive home, he keeps returning to the orphanage. Homer returns to the orphanage so many times that the doctor and the nurses consider Homer a part of the orphanage, and the orphanage is Homer's home.

Homer's first foster family returns him to the orphanage because he never cries. His second family returns him because they beat him and he never stops crying. For a year after he is returned to the orphanage by his second family, he cries at any noise that might mean someone is approaching him. The third family adopts Homer when he is 10. Homer runs away back to the orphanage when one of the adoptive parent's grandchildren fondles his penis and then accuses Homer of fondling his penis. The fourth and final family to adopt Homer is a couple who provides adventure tours to their clients. This couple dies by drowning as a result of logs the Ramses Paper Company are transporting on the river when the couple is swimming in it.
