The records held in the IAU Meteor Catalogue at Lund have been searched in order to find potential Quadrantid stream members, and 188 meteors have been found whose orbits are within pre-set limits (based on the Drummond D‵ criterion) of the mean Quadrantid orbit. Each such orbit has been integrated back in time to 5000 BC, that is almost 7000 yr. The general behaviour of the orbits is fairly complex, but five distinct subsets of orbits can be distinguished, where the general evolutions of the orbits within each subset are broadly similar, but where significant differences exist between the subsets.
