Classify American acting brothers Kieran and Macaulay Culkin, and where can they pass?

[Tooting Carmen]

Prominent mostly during the 90's. They appeared in the first two Home Alone films together, albeit playing cousins rather than brothers. Also interesting is how they both starred in big films in 1991 - Father of the Bride and My Girl respectively - which, moreover, both had "My Girl" by The Temptations in their soundtracks. :D

Yes, vaguely. Well, both Keltics and Baskids are dinaricized so it's just natural that there is some overlapping.
