The Unfinished Tales holds a good deal of information or insights into the little documented people. The names, etymology of the word "wose" as has been said comes from the Anglo-Saxon.

"Wose is a modernization (in this case, the form that the word would have had now if it still existed in the language) of an Anglo-Saxon word wása, which is actually found only in the compound wudu-wása "wild man of the woods."" - (Further Notes on the Drúedain, Unfinished Tales)

It is evident that they have had many names assigned to them during their history, the "Woses" are "Púkel-men", "Drúedain" being the major terms. They were recognised by the Eldar as being enemies of Morgoth and so given the name "Drúedain", singular "Drúedan". This word stemming from the word the "Woses" gave themselves, "Drughu".

"It is stated in isolated notes that their own name for themselves was Drughu" - (Notes, Unfinished Tales)

"This name adopted into Sindarin in Beleriand became Drû (plurals Drúin and Drúath), but when the Eldar discovered that the Drû-folk were steadfast enemies of Morgoth, and especially of the Orcs, the "title" adan was added, and they were called Drúedain (singular Drúadan), to mark both their humanity and friendship with the Eldar, and their racial difference from the people of the Three Houses of the Edain." - (Notes, Unfinished Tales)

This race as has been said were the first men to cross the Anduin;

"Another note says that historians in Gondor believed that the first Men to cross the Anduin were indeed the Drúedain. They came (it was believed) from lands south of Mordor, but before they reached the coasts of Haradwaith they turned north into Ithilien, and eventually finding a way across the Anduin (probably near Cair Andros) settled in the vales of the White Mountains and the wooded lands at their northern feet." - (The Drúedain, Unfinished Tales.)

There is another snippet that might suggest that they reached elsewhere;

"An emigrant branch of the Drúedain accompanied the Folk of Haleth at the end of the First Age, and dwelt in the Forest [of Brethil] with them." - (The Drúedain, Unfinished Tales.)

I would also draw attention to the Drúwaith laur, or "the Old Púkel-wilderness"; the name has certain similarities with that of the Drúedain etymology, and the fact that both of these people dwelt there.

"It is also said here that the identity of the statues of Dunharrow with the remnants of the Drûath (perceived by Meriadoc Brandybuck when he first set eyes on Ghân-buri-Ghân) was originally recognized in Gondor, though at the time of the establishment of the Númenórean kingdom by Isildur they survived only in the Drúadan Forest and in the Drúwaith Iaur " - (The Drúedain, Unfinished Tales.)

The reason for its name was supposedly because there were only a few survivors of the "Púkel-men". Yet if there were "Drúedain" also inhabiting here why would it be solely named after the "Púkel-men". Perhaps Tolkien was saying there was a misinterpretation of the rest of Middle Earth between the distinction between "Púkel-men" and "Drúedain"?

"But in Rohan the identity of the statues of Dunharrow called "Púkel-men" with the "Wild Men" of the Drúadan Forest was not recognized,..." - (The Drúedain, Unfinished Tales.)

Perhaps I interpret this wrong, but is this stating that they are the same. For while the statues are known as "Púkel-men", they were made by the "Drúedain". So while Child of the 7th Age says that people believe they are descendants could they not be the exact same, just a different name?
