You could try the National Archives to see if a copy of the will has survived. There is an index in the Reading Room you can consult. The probability is, however, that all that survives is the reference you found. Another possibility is the Registry of Deeds which might have a record of any property transfer after Theobald Bourke's death. Again, it's a bit of a lottery but staff there are very helpful.
Good luck with the search.
