County of Barcelona
The "Gran Enciclopedia Aragonesa" states that its first material undisputed evidence dates back to a royal seal of Alfonso II of Aragon (1159), and that all evidence about a "Catalan" origin is debatable since historically nothing can be accepted other than the concept of "barcelonès", and understanding that as allusive to the House of Barcelona (Counts of Barcelona), and then, nothing referring to the ancient geographical area known as "Cathalania", "Catalonie" (Catalonia) where the County of Barcelona was found.
