, Leo van de pas "Miroslav Marek website: (Colloredo) Here we find Hieronymus IV (married in 1696) has Anna Maria born after 1710, died 1748, married Norbert Libstejnski z Kolowrat Here you cannot press on Norbert. To me it looks as though Anna Josepha and Anna Maria is one and the same person. Both dying in 1748 seems a good indication. If Anna Josepha/Anna Maria is born earlier, say 1697-1700 she could have married in 1718 and have children starting in 1719. In 1721 a daughter is born who is an ancestor of Crown princess Mathilde of Belgium."
