Res: [tied] TIROL's etymology

Although my great-great-great-grandmother was German from Rhineland, I cannot read German, so I will try to translate this text.

Difficultly. Maybe advises. *Tir-ále. A typical characteristic feature of the little advice broads is the ending ale. With this it concerns a so-called Pertinentiv, i.e. a Lokativ to the genitive. This case has the function, an object or an individual locally and personnel to assign. *Tirále could have signified in earliest ‘ in the area of a person called *Tir-'. Therefore, with Tyrol it concerns a former rätischen area name, just like, by the way, with the name Schenna which advises in earliest from. *Skenja or *Skenje comes what could have signified so much like ‘ to a person called *Skeni severely ’.
After the ending the name is Tyrol comparably with name like Senale (Italian name for our dear woman in the wood), sound ale (ital.-mundartl. Tonàl, German mundartl. Tunōl) and Romallo (ital.-mundartl. Romàl, German mundartl. Ramōl) in the mountain Nons. All these names could be – at least after her ending - rätisch and ‘ have signified in the area *Sen-, *Tun-, *Rum-'.

If I understood correctly what is stated, Tirol came from a proto-form *Tira:le. -a:le seems the Latin suffix -a:lis (cf. dentalis, ruminalis, moralis).
