Phillis was enslaved by John Goodale, then by his wife Elizabeth and then by their son Jedediah.
"John Goodale owned one [enslaved person] named Phillis." - Bourne, p. 408
Frost's probate abstract states that Goodale leaves "to my wife Elizabeth the income of all of my home place with the service of my Negro servants ... till my son Jedidiah be of age, if she continue a widow, using same to bring up my children under age, but after son Jedediah is of age, she shall have 1/2 the income of the home place, 1/2 the house & barn & the service of my 2 Negroes for widowhood only, the other moiety of the house, barn & home place going to son Jedediah Goodale when he is of age, with both Negro servants."
