If you recall, Paddy said that he changed the name of the Fitzgerald estate to Kalinda, in honor of his wife. You may also recall the scene where Charlie was receiving electro-shock therapy; that was inside Kalinda house, because as they said, it was taken over by the government for a short time to be utilized as a certain type of hospital called a "Repatriation Center." The subtext is that Charlie was receiving 'therapy' for his PTSD and homosexuality.
All of this is supported by Charlie's talks with that bar owner who knows all of Charlie's history. The Kalinda house was later given back to the Fitzgeralds when the government was done with it, and presumably that's when the name changed back from Kalinda to Fitzgerald estate (or whatever it's called). When Paddy was speaking with Adeline, she said "how did you know this house was called Kalinda? No one knows that outside of the family."
