I don't believe that they were. When "sealing" came on the scene she was a part of the first ones and none of those involved non-inner-circle peeps of which Jacobs was one - an outsider to their inner circles.
Elder Berry is correct...my understanding is that they only had a secular (i.e. legal) marriage and two children (she was pregnant with the first when she was sealed to Joseph Smith).
