The [[subsidiary titles]] of the earldom are '''Viscount Mountbatten of Burma''', of [[Romsey]] in the [[County of Southampton]] (created earlier in 1946), and '''Baron Romsey''', of Romsey in the County of Southampton (created together with the Earldom in 1947). All these peerages are in the [[Peerage of the United Kingdom]] and have the same [[special remainder]] (see below). 

''Lord Romsey'' was the [[Courtesy titles in the United Kingdom|courtesy title]] by which Lady Mountbatten's eldest son and heir was known until in 2005 he succeeded his father [[John Knatchbull, 7th Baron Brabourne]] as [[Baron Brabourne]], of [[Brabourne]] in the [[County of Kent]]. Subsequently, with the death of his mother on 13 June 2017, he became the [[Norton Knatchbull, 3rd Earl Mountbatten of Burma|3rd Earl Mountbatten of Burma]]. As a consequence, both the Brabourne peerage and the [[Knatchbull Baronets|Knatchbull Baronetcy]], of [[Mersham|Mersham Hatch]], in the [[Baronetage of England]] (created in 1641 for [[Sir Norton Knatchbull, 1st Baronet|Sir Norton Knatchbull]]) became subsidiary titles to the Earldom. 

''Lord Brabourne'' is now the courtesy title by which Lord Mountbatten's eldest son is known.<ref>[https://metro.co.uk/2019/01/12/prince-charless-godson-gets-engaged-professional-mermaid-8336521/ "Prince Charles’s godson gets engaged to a professional mermaid"],  [[Metro (British newspaper)|Metro]], 12 January 2019</ref>
