Carole references the NEHGR 2000 article below. It's a great article and should be read by any Bullard researcher. I've excerpted pieces of it into the narrative of William Bullard-84.
Of great interest and in response to this query here is that William Bullard's wife was neither Grissell or Griswold. First Griswold was an error. Second, Mary was the WIDOW of Francis Grissell (not Francis Griswold). Therefore, her LNAB should be Unknown.
There was no wife Mary Tracy.
The wives of William Bullard of Dedham were:
____ ____. This unknown wife was the mother of his children!
at Dedham, MA 4 Jan 1653 Mary (_____) Grissell, widow of Francis Grissell. She died in Charlestown 17 May 1685.
I recommend that you change Mary Tracy-203 to Mary Unknown since no children are currently attached to her. She then should be linked to Francis Grissell. Actually see if Francis Grissell has a wife already; if she's unknown, merge Tracy-203 into her.
Then change either of Grissel-1 or Griswold-265 into Unknown Unknown, the mother of William Bullard's children. Merge the other one into the Unknown-#####.
Clear as mud?
