Hi,
These records are now available on An*****y which I have checked this morning. The ONLY entries that I can find, 1571-1577 are as follows:-
St Mary, Painswick, PRs
Isbel HUNT(?), dau of Thomas HUNT(?) baptised 20th June 1577
Isbell HESS, dau of Thomas HESS baptised 29th September 1573
You could try accessing the An*****y index for Gloucestershire to see if the baptism you are looking for is there, but be warned, the index, which you can search by name, is somewhat suspect, as these were transcribed in China!
