No, actually the Homer placement is logical in terms of migratory patterns. I get the impression from seeing other Heustis (or Huestis) genealogies that the family came from Holland, immigrated to New England and then generation by generation moved west. There's a big group that moved from Vermont to Crown Point, NY. If you look at Google Earth, Homer is just above Cortland, and then as you move up between the finger lakes you come first to Sempronius (home of Benjamin), and then on to Auburn. My hunch would be that as you can trace Benjamin back, you might either find him in Homer, or both him and John in some earlier (and more easterly) place.
Lydia Sophia Heustis was my great-grandmother, though she died long before I had a chance to meet her. My mother was named after her, and one of my mother's aunts inherited the name Almira as a middle name.
