Hi Greg! I have ties to this line. I show Conrad Dotterer married to Esther Berge(y). They had 11 children, Ann, born 5 June 1822 and married to Joseph Dockey, then married John Leister. I have a gg-grandfather named Isaac Dotterer/Dettrey from this family. He married 1st. Catherine Bordner, then 2nd. Sarah J Madrick. I do not have any other information on Ann Dotterer at this time. The Barbara Esterlein that you mentioned, married Abraham Dotterer who was the Grandfather to Conrad and Ann Dotterer.
