Daenerys is an English (Modern) feminine name invented in the 20th century. It is beginning to gain some traction in real life. Daenerys was used for 21 baby girls in 2012. The name may be associated with Welsh name “Nerys”, from the Middle Welsh “ner”, meaning “lord, chief” plus popular suffix “-ys” (found in Carys, Dilys, Gladys and Glenys). In turn the name means “lady”. Daenerys Targaryen is a fictional character in the "A Song of Ice and Fire" series of novels by American author George R. R. Martin, and its television adaptation Game of Thrones.
