Mira was one of two daughters born to Fortune and Dinah.
She was born on December 19, 1788, and would have become
free on her 24th birthday. Mira was nine or ten years old
when her father died.
It is not known what happened to Mira after Fortune died
in 1798. She does not appear to have been in the Porter
household in 1800; the census data for that year records
only two African Americans, probably Dinah and a young man
named Luke, who appear in Porter's estate inventory taken
Connecticut legislation prevented the sale of slaves outside
of the state after 1788; if the Porters sold Mira, she would
most likely have remained in Connecticut.
