Why Would The White House Dinner For Scandinavian Leaders Hold Interest For Irish And Irish-Descended Americans?

As the POTUS And the First Lady host Scandinavian national leaders at a White House dinner, some Irish and Irish-descended Americans might want to pay attention. Among those whom want to pay attention to (as far as I know) milestone White House dinner:

1. McLaughlins (e.g., pollster John McLaughlin and Baseball Crank's Dan McLaughlin)
2. O'Reillys (And Reillys, Etc.) (including me, as my mother's late paternal grandmother is a Reilly—thus, by the way,  my Reilly's name)
3. Goulds whom are Irish [as opposed to Jewish] 
4. Reynoldses

Two and Four, by the way, apply to four of my relatives (whose names and relationships to me I will not disclose for the sake of their privacy).
