History:
Families might have moved for better jobs or to marry, carrying this surname to new places. Wars or other big changes also forced some people to move, taking this surname with them. Where this surname is common today depends on these movements – some areas have more people with this surname because of specific events or families staying there a long time.
Description:
However, I can guess at similar surnames based on how names usually change. We might see Valaki (a small sound shift), Valek (a shorter form), or Valakas (maybe an added bit or a different regional spelling).
