As Paula noted, it will be useful to explore alternative spellings of places; and I have found Maine census-takers spelling my ancestors names Wiley, Wilie, and Wylie. The -scot suffix was used in Abenaki place names referring to large rivers, or possibly the estuaries at the mouths of such rivers.
