Franz Wilhelm and his son George have a relationship. When George was young, their relationship was not public knowledge because George was raised by his mother Maria, who had custody of their son, as well as by his maternal grandparents Vladimir and Leonida. However, Franz Wilhelm did have visitation with George. There have been some very cute pictures shared by the House of Romanoff Instagram account of young George with his father and one of his Prussian aunts.
In 2011, George attended the wedding of his cousin Georg Friedrich to Sophie. He accompanied his mother; however, his father also attended with his now wife Nadia. The four of them were not photographed together. However, in 2017, at the Leiningen/Preussen wedding, there was a charming picture of George, his parents, and his eventual stepmother walking through the hallway of (guessing) Amorbach. In 2019, it was George who announced on his Instagram account the marriage of his father and Nadia: "Congratulations to my father that recently got married to this beautiful lady."
Since George and Victoria’s engagement and marriage, Victoria has shared many more photos of Franz Wilhelm with the family on her Instagram.
