Boyd Porterfield, the pursuer, claimed that he was entitled to the lands of the Porterfield family in Hapland following the death of his cousin, Gabriel. Boyd was the grandson and heir of Alexander Porterfield, who, in turn, was a cousin of Gabriel Porterfield. In 1716, Gabriel granted a bond of tailzie to Alexander. Boyd claimed that he was entitled to the lands based on the tailzie. Gabriel's three daughters, Joanna, Margaret, and Lilias, along with their husbands, challenged Boyd's claim to the lands and sought to control their father's estate.
