 Seeing as how both the Knights Hospitaller and Knights Templar are involved in Riseley history back in 1279 it has been suggested that the two organisations have been confused for each other somewhere along the line.There is evidence of Riseley being affected by the Black Death back in 1351 when 300 acres of arable land became worthless due to them being uncultivated and no one occupying them.During the Middle Ages, 1346 to be exact, Riseley was also home to a murder when William Petersoil, a member of a family which owned a manor in Riseley named the manor of Petersoills (or Petersoyles), was murdered.
