>>>Are you referring to the notion that the Albanians are descended from the Dacians or the Thracians? The ALbanian and ROmanian languages do have a good deal of similarities, despite occuping different language family branches of Indo-European. However, the original Romanians/Vlachs probably originated from the S and Central Serbian/Northern Macedonian/NW BUlgarian and NE Albanian area. By the way, I'm sorry about the tagline from my previous post.
Well, the mainstream theories have them descending from either Illyrians or Thracians, or some type of mixture of the two. However many Serb and Macedonian historians and certain Greek historians, completely put aside this notion and claim that the Albanians didn't come into the Balkans until the 15th century from the Caucasus, and they cite Caucasian Albania as proof.
The following paper discusses (among other things) the apparent similarities between Albanian and Romanian.

However further than that I have to plead ignorance for etymology/linguistics is only a hobby for me.
