Romanian prince, the eldest child and only son of Princess Elena of Romania and Robin Medforth-Mills. As a grandson of Michael I, the former king of Romania, he was third in line to the defunct throne of Romania according to a new family statute enacted in 2007, that also conferred the title of a "prince of Romania" on him which was abrogated in 2015. The statute and the titles it confers have no standing in present Romanian law.
Until the age of 4, Medforth-Mills lived with his sister and parents at the Romanian royal family's residence in Versoix, Switzerland. The family moved to England in 1989 where they took up residence at Flass Hall, Esh Winning in County Durham. As a descendant of Queen Victoria of the United Kingdom and King Christian IX of Denmark, he regularly met with many of his extended relatives.
Medforth-Mills' first major appearance in Romania was on 19 April 1992 on Easter Day along with his grandparents King Michael I and Queen Anne and with his mother and her second husband Alexander Nixon.
The exclusion of Nicholas from the royal succession was due to the birth of an illegitimate daughter, born from a short relationship with Nicoleta Cîrjan. The child, born 9 February 2016 and named Iris Anna, was not recognized by the former prince. However, on 27 May 2019, Nicholas confirmed via a Facebook post that paternity tests had confirmed the illegitimate child is his, and that he had assumed legal responsibility for the child.
Nicholas became engaged to Alina Maria Binder, a Romanian journalist, on 29 July 2017 in Cornwall. They married civilly in Henley-on-Thames on 6 October 2017.
