As @Kathar1na. said quintana has now no meaning for us. In Galician should be quintá like hermana/irmá or mañana/ mañá, but the word quintá would still be less understood.
In relation to the meaning fifth, Quintáns I think can do with it, because Quitáns is the plural in Galician of Quintán (masculine).
Quintana (feminine), plural "quintanas" could be also a house or a space.
In Madrid there is a neighborhood and a Metro station called Quintana. I didn't find on internet the reason of the name (house or space).
In Mexico, Quintana Roo state sounds like a person name.
On my Santiago Fisterra I met a Korean pilgrim who had a very bad English. It took time to know that her favourite Spanish food was gambas al ajillo. I also like pollo and conejo al ajillo.
I watched it on Spanish TV yesterday. The remains are in a very good condition.
The people of Al Andalus were much cleaner than the Christians. No doubt.
