Currently the profile for Abigail Bull (b. c. 1653, dtr of Thomas Bull (immigrant) of Hartford, says she married three times
____ Buck after 1684
James Curtis Nov. 19, 1691 in Hartford, CT
Anderson says she married instead Rev. Thomas Barnard of Andover, Mass, in Salem, Mass (roughly 120 miles), but apparently Thomas was born in Hartford and raised in Hadley, Mass until he went to college (so maybe).
The town record says: Abigail Bull, Mrs. [of Salem, dup.], and Thomas Barnard, widr. [at Salem, dup.], Apr. 28, 1696.
Sometimes Mrs. does not mean a married person. She was 43, rather old for a first marriage.
On the other hand the marriages to Buck, Curtis and Roby don't hang together well. I've added sources to Abigail's profile in the Research Notes.
Short Story. Her father's 1684 will calls her by her maiden name. But Savage for some reason says that his will calls her Abigail Buck. We know this is incorrect. So the first step in the chain is broken. Abigail probably never married an Unknown Buck between 1684 and 1686.
Then the marriage record of James Curtis does not list a brides surname. Abigail could just as easily be Smith as Buck or Bull.
Abigail, the widow of James Curtis did marry the widower Andrew Roby.
I believe we need to change the wife of James Curtis and Andrew Roby to Abigail Unknown, eliminate (make him disputed) Unknown Buck and then marry Abigail Bull of Hartford to Rev. Thomas Barnard.
