as I mentioned earlier "The Cantacuzino or Cantacuzène family is a Romanian aristocratic family that gave several Princes of Wallachia and Moldavia, descending from a branch of the Byzantine Kantakouzenos family, specifically from the Byzantine Emperor John VI Kantakouzenos (reigned 1347–1354). After the Russo-Ottoman War of 1710–11 a lateral branch of the family settled in Russia, receiving the princely (Knyaz, as opposed to Velikij Knyaz) status. In 1944 Prince Ștefan Cantacuzino settled in Sweden, where his descendants form part of the unintroduced nobility of the country." https://en.wikipedia.org/wiki/Order_of_Saint_Lazarus

"The 49th Grand Master H.R.H. Prince Pieter Cantacuzino
Elected as Grand Master at the GMCM in Göddöllö, Hungary in June 2013" "The Cantacuzino or Cantacuzène family is a princely family of Wallachia, Moldavia and Russia, a branch of the Greek Kantakouzenos family, descended from the Byzantine Emperor John VI Cantacuzenus. The genealogical links between the Byzantine Greek and Romanian Cantacuzinos have been extensively documented.

In 1944, The Grandmasters father, Prince Ștefan Cantacuzino settled in Sweden. In 1961 he introduced the Order in Sweden together with Dr. Bela De Kezdy and the now Prior emeritus of the Grand Priory of Sweden H.E. Baron Eric M. Engzell. The former Grand Prior of Sweden, H.H. Prince Andronic Cantacuzino (deceased in 2009) was an elder brother of the Grand Master."
