Tracking some history-- I have family information that a Hastings Sandridge (grandson of William Sandridge?) fathered a child with his slave recorded only as "Eliza" with a last name possibly as Brown. Eliza and Hastings child was Jenny Brown, b.1857, d.1946.
Any additional info on Hastings would be welcome. It would stand to reason that "Hastings" is really Thomas Hastings Jr, since many Jr.'s go by a middle name to avoid confusion in the household.
