Note that the index numbers are only technical numbers which have no persistence. After a new system generation is done, all of them are invalid. To generate a persistent link, use the name.There are more than one people of this name. Therefore additional info should be added to the URL. Usually, a birth date or death date will do, an alternative is the title. Note that the dates may contain question marks, spaces, or slashes! Replace spaces by at-signs (@) and question marks by percent (%). A date with slash is not usable.Use the URL:
