ThuLines are suggesting that Ann Thompson's mother is Mary Colvard and her grandfather John Colvard.
On clicking on the tree that has this information I can see that Ann's father is John Thomposon. His marriage to Mary Colvard is attached:

Name John Thompson
Event Type Marriage
Marriage Date 4 May 1783
Marriage Place Wakefield, All Saints, Yorkshire, England
Parish as it Appears Wakefield, All Saints
Spouse Mary Collard
Household Members Name
Name John Thompson
Name Mary Collard
Mary Colvard's (Collard) parents are given as John Colvard and Elizabeth Broadhead.
I think the baptism given for Ann (at York, some way away) is incorrect, consequently I looked again for a possible baptism. Ann is given as having been born at Stanley, Wakefield, from the censuses.
Other children of John and Mary Thompson:
Richard 29 May 1787
Hannah 4 October 1788
Mary 14 September 1791 - all three at All Saints, Wakefield
Sarah 16 April 1797 St John Wakefield - and this states after the mother's name "daughter of John and Elizabeth Colvard"

In 1804 there is the non-conformist birth of Fanny Thompson, also with the parents John and Mary.
