Living as a (expat) Kevin in The Netherlands for many years and I've never heard this. Might be that my friends are just polite. Interested to know if this is well-known to those who grew up in The Netherlands.
Home Alone came out in 1990.
Kevin does have some lingering association; the lower socio-economic class stigma is there, but not that strong. Keep in mind that for someone born in an Anglo-Saxon country, that stigma would not necessarily apply. It tends to be limited to Dutch-born folk.
Chantal on the other hand seems to carry a much stronger connotation of a lower class background.
