Hello Kristin,
I went to the Berkshire Record Office yesterday and did your look up. The news is not good I'm afraid, but I have listed exactly what I searched for you - for your records.
The Archivist at the Record Office was very helpful, as usual, there are many parishes for Reading but however for the time you are interested in there were 3 - St.Giles, St.Marys, and St.Lawrence
St.Mary's Vol. 1 Bound Volume 1538 - 1812 Transcriptions of Parish Registers
Checked Baptisms - 1600 -1617 no Ferris shown.
Then found an index !
Ferris Index
Anne - p203, Catherine - 17, Elizabeth- 192, Francis - 184,
James - 12, Margaret - 3.
Have listed entries as thought they may be useful?

There is no transcription. Microfilm.
Unfortunately many of the early pages of the film are barely legible, some have suffered such damage that it was very difficult to make out anything, I had problems trying to find the relevant years, I'm still not certain that I did. I really just didn't feel competent to do this search on this microfilm the writing is extremely difficult to comprehend. I have read microfilm before but only back to 1700 parish registers this was just extremely difficult and I had to give up after about an hour - sorry.
