Historically all members of a noble family were generally titled. If the family was of the rank of a Count or a Baron, all members received that title as well. However, following the new Instrument of Government from 1809, a change was made more in line with the British system so that, for later nobility, only the head of the family would hold the title (if there is one). There are a few families where these systems overlap such that the vast majority are nobles pre-1809 without title, while the heads of the families have been elevated to count or baron after 1809. The vast majority of noble families are still of the old kind where all members are regarded as nobles.
