    Lou Poole thinks that Thomas Moore's daughter was Priscilla who married Edward Champion
Walton, Elizabeth, Leg. Thomas Moore D. 23 December 1675 R. 9 August 1676
  wit: George Moore, Margaret Williams, Priscilla Champion  
  Lou Poole says he has no clues as to how Elizabeth Walton is related to Thomas Moore. as he is sole legatee of her will.
    but a good guess would be she was the mother of Thomas Moore's wife.

This is my working hypothesis - the way I see it as of this moment!! 
from Dr. Barry Hayes' research

observations by Dr. Barry Hayes:
1. The father of Edward Champion, who appears to have married Priscilla, may have been an Edward, the first husband of Mrs. Elizabeth --?-- Champion Poole Walton (1612-1676).. However, there is no clear documentary proof of the given name of Elizabeth's first husband, --?-- Champion. Other Champions were around.

2. The fact that the matriarch Elizabeth (1612-1676) made Thomas Moore her sole legatee in 1675 when she made her will does not necessarily imply a "blood" relationship.

3. Thomas Moore probably married Elizabeth's daughter Elizabeth Jr., who would have been the widow Elizabeth Eldridge who clearly married 2nd Thomas Moore.

4. The circumstantial evidence is strong that Phyliss Fort was the daughter of Elizabeth Sr.

5. The circumstantial evidence is strong that Mrs. Priscilla Champion was .... a sister of the proved brothers a.Thomas Moore and b. George Moore, also possibly, c. John Moore Jr and d. William Moore who patented in 1652 in Nansemond just to the east of John and e. --?-- Moore and his wife Mrs. Anne Rogers Moore Baron Matthews Davis, whose only Moore son was yet another John Moore, f. Elizabeth Moore who married 1st Thomas Barlow and 2nd William Baldwin, and g. Katherine Moore who married 1st unknown and 2nd Robert Flake.
