I have a family of Adamses who were in Centre County sometime around 1860. Three known siblings, John (born 1837), Hugh (1845) and Sarah, or Sadie (1848). This would make their parients born around 1815-17.
Obviously they are not out of William Townsend's line, but I'm wondering if he may have had any brothers who migrated along the same route.
Sadie got her teaching certificate in 1868 from Port Matilda, Centre Co School District. I've been told she, or possibly her whole family, later migrated into Missouri to evade a tuberculosis epidemic.
