After the marriage of Michael I and Anne, Helen returned to Villa Sparta in Fiesole. Through 1951, she hosted her son and his family, who visited with her at least twice a year. Over the years, the family of the former king grew with the successive births of princesses Margareta (1949), Elena (1950), Irina (1953), Sophie (1957) and Maria (1964). From 1949 to 1950, Helen also housed her sister Irene and her nephew Amedeo, who later settled in a neighboring residence. Over the years, the two Greek princesses retained a strong bond, which ended with the death of the duchess of Aosta in 1974. Throughout her life, Helen also remained deeply attached to Amedeo and his first wife, Princess Claude of Orléans.
