i think ive found for Johns wife Janet (or Jennet as SP has it) 
it's not 'as SP has it'. It's transcribed as it appears in the original document, so it's 'as the clerk at the time would have it'. 
Jennet appears 21,948 times in SP, compared with 108,502 appearances of Jannet and 2,819,533 of Janet. Plus 1,373,756 of Jessie, which in Scotland is interchangeable with Janet.
