• Notes

  Looking at the Ancestry trees there is a common belief that Isabel's parents are George and Ann nee Case. Given Isabel's DOB based on her age at death, I am happy that she was born/baptised in 1747. Family search returns only1 suitable set of parents George Postlethwaite and Ann. Family Search and the Lancashire Online Parish Clerks only find one suitable match and so I have gone with that.
