There was a Mary (Godwin) Rice, widow of (probably) Francis Rice, around 1725 or so. Francis died before 1695 in Warwick, so this information fits like a glove, in my opinion.
I have a copy of the report by Sir John Randolph, I would like to see the other source:
Virginia Colonial Decisions p.R109 1Iones vs. Langhorn. Detinue for Negroes Fr Deft. The case. Mary Godwin being possessed of several Negroes by her Will disposed of them in this manner, “My Will is that after my Debts and legacies paid my Daughter Mary Rice shall have the use of my whole Estate Real and Personal after she comes to the age of Years, during her natural Life, And if my Dau’ter shall leave heirs lawfully begotten of her Body, that those Heirs shall have my whole Estate &c.”
She married Myres, & Myres and she by Deed Mortgaged the Negroes to the Plt. And had Issue 4. Children, and she is now married to the Deft. Langhorn and has four Children by him
The only Question is, Whether a Thing, of which the Wife has only the use may be disposed of by the Husband, so as to bind the Wife  after his Death, For the Deed made by Husband and Wife, is the Deed of the Wife only during Coverture and shall not bind her after the death of her Husband, and I think the Negroes here, of which the Wife had only the use cou’d
1 S.C. in W. G.’s Barradall 15, and printed in Jeff. 37. but not the same report.
[Note by W.G.]
only be sold for the Life of the Husband and after his death the Wife shall be restored to the use of them.
This is a previous post on the Genforum.
I copy it here as a reference. I believe our Francis Rice of Henrico/Amelia/Prince Edward Counties from 1731 on through 1770 is descended from this family. The Edward Rice in Warwick on 1704 quit claim rolls is possibly another son of old Francis, or else a brother.
I am trying to find more information on this Rice family in Warwick.
