I don't know if this would be of any realtionship but I have noted a Susuan Aitken of New Brunswick, Canada who married John Grant (he was born in 1822 Lunenburg ,NS) migrated through Eastport ,ME in 1848 and settled in the Boston,MA area, they had at least 2 children ; Walter C. Grant and Jeanette A. Grant . Apparently Susan died at a young age.I have dates but not at hand.
and I have nothing more on her . I have been trying to locate her parents with no avail.
Best Wishes ,
