I am also looking at this Teague family from Nobleboro, and trying to find siblings and connections with my family.The following text establishes a link between 3 siblings:Isaac, Ezra, and Asa.
Altho, I don't know if the Isaac Teague who married Jane Hussey is the Isaac Teague that went to Farmington!
