Someone at FamilySearch thinks an Elisha Clark died in Milton in 1809. This census shows him with a wife, 6 sons and 2 daughters.
A couple lines down on that census page is a David Judson, age 26-45. On page 2 is a John Clark, age 45+, Abijah Clark age 26-45. "Abijah" might be Lois's nephew Elijah who would have been 42.
On page 6 is someone who might be Ephraim Judson. The name is hard to read and familysearch transcribed the name as Sudson. He and his wife are 45+, there's a son age 10-16 and a daughter age 16-26. The line below is for an Andrew Judson or Sudson age 26-45 with a wife and 3 small children.
