I have put all English names, including Catherine, into their modern form. I have anglicised French ones (on grounds of familiarity) and put those in all other languages into their modern form in the relevant language (Juana and Juan and Sebastiano). Foreign titles (Duke, Archduke, Commander) are also anglicised. A few names, such as Ferdinand of Aragon and Catherine of Aragon, have breached the rules, once again on grounds of familiarity.
