I believe it was the father.... From his father's bio it says ...
The will of Ebenezer Sherman of Marshfield, “labourer” dated 10 January 1759 and proved 14 February 1759, mentioned his sons: William (eldest), Ebenezer, Elisha, Robert and John; daughters: Rachel Joyce, Elizabeth Witherell, Abigail Carver, and Barsheba Walker; and his wife, Bathsheba Sherman[6]
Bathsheba is not mentioned as a wife for the elder Ebenezer Sherman. His first wife died in 1726.
