In December 1629, the life of Agnes Sinclare of Burnehead, Haddington, became inextricably linked to the testimony of Alexander Hamilton. Identified by the judicial records as a warlock, Hamilton specifically denounced Agnes as a "known witch," effectively marking her for state intervention. This denunciation, recorded on December 4, 1629, was the catalyst for the legal proceedings that followed, placing her among a wider group of individuals named by Hamilton during this period.
By April 1, 1630, official case records (C/EGD/1137) were opened against Agnes in relation to these accusations. While the Register of the Privy Council acknowledges the existence of her case and her subsequent entanglement in the judicial system, no surviving documentation details the specific arguments presented at her trial or its final outcome. Agnes remains a figure defined by the formal record of her denunciation, existing within the administrative machinery of the early seventeenth-century Scottish legal system.
