Valley or river
Tayia is a rare name often considered a modern variation of Taya or a diminutive of names like Natalia or Taylor. In some contexts, it is associated with the River Tay in Scotland, suggesting a connection to flowing water or a valley. Its usage is contemporary and lacks a singular, ancient etymological root.
