It seems to me that it is misspelled even in Basque, at best see it read.
Yes, it is well written. It does not come from reading, nor is it "leira" (orchard). "Leria" is a mess.
Leria or better Lería, is the name of a Spanish town, which belongs to the municipality of Yanguas, in the Province of Soria, Autonomous Community of Castile and León. It is currently uninhabited.
