The name likely originated as a topographical descriptor for someone who lived near or owned a castle, or perhaps as a habitational name from a place called Caisteal or something similar. Like many Scottish surnames, it is believed to have originated in the Highlands. Variations in spelling can occur due to historical transliteration and regional dialects.
