Kallio Family History
Kallio Surname Meaning
Finnish: ornamental name from kallio ‘rock’ widely adopted during the name-changing campaigns in the late 19th and early 20th centuries in southern and western Finland in part to replace Swedish surnames especially those containing the elements berg ‘rock’ or sten ‘stone’ (compare Laine).
In some cases, however, it is a habitational name from farms so named.
