My take on the 'krill' name is that an enumerator misheard Grill (maybe because of an accent) and wrote what he heard. That's how many names get massacred on censuses. One of my family names, Spaulding, is a change from Spalding or Spalden. Meddaugh can be spelled so many ways, it's scary, and that was my mom's name. Her dad spelled it Meddaugh, but HIS dad spelled it Middaugh. And there is Middach, Meadow, Medder, etc. So, Krill is really close to Grill!
