The Ely Ancestry, pg. 259, indicates the first first of Samuel Griswold Goodrich was Adeline Gratia Bradley, the daughter of Stephen Rowe Bradley and Gratia Taylor. All indications are that one of Stephen Rowe Bradley's wives was named Thankful Taylor, who died in 1802, two years after Adeline was born. Consequently I have assumed that Gratia, the wife of Stphen Rowe Bradley, and Thankful are one and the same person.
