You currently have Christoffel listed as being archaic in the Dutch-speaking world, i.e. it is no longer in use. That is incorrect: there are still living Dutch and Belgian bearers of the name, some of which you can find on Facebook and LinkedIn. As such, the name is just rare instead of archaic:• https://www.meertens.knaw.nl/nvb/naam/is/Christoffel (in Dutch; shows the prevalence of the name in the Netherlands in 2014) • http://www.names.be/voornamen.html?met=Christoffel&sort=beldesc (in Dutch; shows the prevalence of the name in Belgium in 2009) • https://be.linkedin.com/pub/dir/Christoffel/+/be-0-Belgi%C3%AB (lists only bearers living in Belgium) • https://nl.linkedin.com/pub/dir/Christoffel/+/nl-0-Nederland (lists only bearers living in the Netherlands)I will concede, though, that Christoffel is on the way of eventually becoming extinct. It is very rare among millennials and almost non-existent among zoomers (Gen Z), so once these generations and the ones before them have expired, the name will be truly obsolete. That fateful day is still a couple of decades away, however. [noted -ed]
