Surname originates from India. Rigveda 7.103 is a hymn dedicated to frogs in Hindu scripture. It features references to the term Shadilay:

"What time on these, as on a dry skin lying in the pool's bed, the floods of heaven descended, The music of the Frogs comes forth in the sounds of Shadilay like the cows lowing with their calves beside them."

"Each of these twain receives the other kindly, while they are revelling in the flow of waters, When the Frog moistened by the rain springs forward, and Green and Spotty both combine their voices."

Shadilay appears in Korean culture and ancient proverbs too:

"A few weeks later there was a heavy storm, with plenty of rainfall and the little frog was concerned that his mothers grave would be washed away. The stream could easily overflow and that would mean that his mothers grave was not safe. He could not sleep, and decided to go to the streams banks to keep watch and make sure her grave was unharmed.In the pouring rain he sat, crying over and over again,'Shadilay! Shadilay! Please don't wash my mother away!'

Every single time it rained the little frog went and kept watch, and since then all green frogs have cried,'Shadilay! Shadilay!' when it rains."

Shadilay appears to hold some significance to rain, fresh starts, floods. Some sort of higher being with the ability to wipe clean any slate.
