This is the only one I found but there are over 1,000 Brooks listed in Warwick on the IGI so she might be among those - I just had a cursory look.
Nothing came up in the search with Warwick with any of the variations you supplied.
1. Adela BROOKS - International Genealogical Index

You will need to access Parish records - do you know who her parents were? that would be a help or who she married would give you a parents name and an address to go on
