I'm looking for a murder ballad said to have been composed about a triple murder in Killingworth, CT, USA in 1779. Here's a contemporary account.
NEW LONDON Oct. 20
The following tragical affair happened at the north parish in Killingworth on Wednesday last, viz. the wife of Mr. ___ [Horace?] Higgins of that parish, being disordered in her reason, and being left in the house with three of her children, she called her son of seven years old, to her, telling him she wanted to pin his collar, and immediately cut his throat, she then cut the throats of her daughter of five years old, and her infant which lay on the bed: Mr. Higgins soon after coming into the house, found her on her knees, cutting her own throat with a dull knife, which with some difficulty he wrested from her; but she had wounded herself to that degree she died soon after.
Continental Journal [Boston, MA] 28 October 1779: p. 3

Later stories (1885 and 1886) say that there was a poem written by a local writer and a song about the tragedy, but do not indicate when these were written. I'm trying to locate either of these texts. Thanks for any help!
