Dinah was enslaved by Elizabeth Storer.

"Sharper Negro servant to widow Mary Hill and Dinah Negro servant to widow Elizabeth Storer their intentions of marriage were entered the 29th of March 1776."

If this Elizabeth Storer is related to John Storer, then this Dinah may be the Negro woman that is noted in his probate record in 1768.
