OK, if nobody else is interested...
Rog was the strongest of the Noldor in the BoLT Fall of Gondolin - true.
róg = wose in the true language of Rohan, according to UT, The Drúedain - true.
However, Rodyn (the weekday dedicated to the Valar) was also called Orbelain in Sindarin. This one's a lie.
(Alliteration appreciated!
