 Ferdinand Victor Jean von Prondzynski was born at Bevensen on 30 June 1954.The family home at Breese had to be partially demolished in 1958, because of structural damage to two wings during the war and immediate post-war years, and Hans and Irene, with their Ferdinand and two sisters, Isabelle and Pia, moved to a farming estate in Ireland in 1961.According to Prondzynski, his father's poor health, lack of funds to maintain Breese im Bruche, and a desire for a less stressful lifestyle, led to Hans and Irene von Prondzynski leaving Germany and moving to the Knockdrin estate near Mullingar, County Westmeath, where they settled in Knockdrin Castle.
