Aubrey Atwater of Rhode Island is (or was?) a UU. She usually performs and records with husband Elwood Donnelly as Atwater/Donnelly. They also work in other configurations: the Atwater/Donnelly Trio, the Atwater/Donnelly band, and Jerimoth Hill. Much of their music is in the Appalachian and Celtic tradition, but they also do some original songs. With Jerimoth Hill, they recorded songs of "White Gospel music." That project was largely led by Elwood.
