Early Life
In her memorial inscription (see below) Ann's date of birth is suggested to be 1748 (36 years prior to 1784) but I can't find any baptismal records for this date. Instead, baptismal records for an Ann Healey, daughter of John Healey, baptised 3
rd February 1752 at All Saints in Wakefield are generally used by other pedigrees. This means she would have been 32 at the time of her death, rather than 36.
Death
Presumably Ann died of complications of childbirth with her daughter (also called Ann) as she died on the 16
th of May 1784, just a few weeks after the birth of her daughter on the 22
nd of April.
A memorial flagstone at St John the Evangelist in Leeds reads:
