My sixth greatgrandfather, Samuel Fuller, wasn't just a murderer - he was executed for the killing of his own son:
WINDHAM COUNTY NEWSPAPERS : WINDHAM HERALD 1791-1795 (Connecticut)
575. WH Sat Dec. 8, 1792: "Pittsburgh, November 8. On Friday the 2d inst., was executed in Hillsborough, Orange County, North Carolina, Samuel Fuller, of Granville County, for the horrid and unnatural murder of his son. Mr. Fuller, till within a few years past, has conducted himself as a good and respectable citizen, has raised a family in good repute, and by his industry and frugality, acquired considerable property. Unfortunately for mankind, their passions, in some unguarded moments, get the better of reason and every human feeling, in the present case we have a striking instance. A man near three score years of age, unworthily takes to his bed an abandoned woman, and keeps her in offence of a faithful wife and a number of children, who are the pledges of his marriage vow. The unhappy one who fell a victim to his rage, had frequently requested his father to drive this infamous woman from his house, who destroyed the quiet of all the family. On the morning of the fatal catastrophe, this son went with a resolution to drive her off, when high words ensued, and soon after a gun was discharged by the father at his son, loaded with buck shot, several of which perforated his head and body, which killed him instantly."
The story spread from NC, to PA and thence to CT. Nobody knows the name of the son he killed: the one most often proposed was his son Spivey, but he was living in GA at the time, and Samuel included him in the will he wrote before his execution.
