Robert Doney was the son of Wane Doney who deeded land for a mill on the Kennebunk River. After King Phillips War, he was imprisoned along with other Indigenous people and sent to Boston.

"The Town of Cape Porpus granted many Kennebunk River lots in April of 1681. One of those granted Joseph and Edmund Littlefield and Nicholas Cole the right to build mills between Goff's Brook and Durrell's Bridge. According to Charles Bradbury in his History of Kennebunkport, their plans were abandoned when upstream neighbors objected to a dam at that location. One month later, Wane Doney, Sagamore of Kennebunk, deeded the mill men another piece of land way upstream, above the Indian lodges, where Route 1 now crossed the Kennebunk River. His oldest son, Robert (Robin) Doney, witnessed this instrument, which is still in the manuscript collection of the Boston Public Library." - Cummins, Sagamore Doney's Kennebunk River Warriors

Relations deteriorated in 1685. "English cattle were allowed to wander free through Indian cornfields in Saco after repeated complaints. Every source of food the Indians had was threatened. They were angry and vocal about the total disregard for the terms of the Treaty of Casco. Threats were made. Some wandering English cows were killed. As a precaution, in September 1688, Justice of the Peace Benjamin Blackman of Saco gathered up 16 to 20 Indians who had been leaders against the English during King Phillips War. Among them were the Hegens of Saco and the Doneys of Kennebunk. The prisoners were sent to Boston and their brethren began rounding up English hostages to exchange for the prisoners. A month later, letters were sent to and from Gov. Andros notifying him that "ye 11th instant one man was found killed by Indians to ye Eastward att Cape Porpus & serverall others missing who are feared to be lost." - Cummins, Sagamore Doney's Warriors

"There were other connections as well between the Indians of the Kennebunks and their neighbors. The Dony (or Doney or Donany) family were sachems in this area in the 1680s, when 'Wane Donany sagamor of Kennebunk' sold two parcels of land in the Kennebunk region. One of these deeds was made 'with the consent of Robert, my eldest son,' and indeed 'Robbin Ingene' witnessed the other sale. (footnote 58 - Wane Doany to Joseph Littlefield et al., 2 May 1681, Boston Public Library manuscript collections, Boston; Nacodumiah to Harlackenden Symonds, 11 August 1686, York Deeds, 1689: 86, Wayne Doany is referred to in this deed as 'Nacodumiah, called by the English by the name of Dony.')" - Baker, pp. 88-89
