Mary Tolor, Mary Davis Catherine Halket

I recently discovered that my ancestor, John Berry (c. 1701-1778) of Killinlahan, otherwise known as Broadwood, in the Parish of Castletown, Kindalen, Co. Westmeath included bequests in his will "To sister Nugent 10 per annum for life. To natural daughter Mary Davis 10. To children of natural daughter, Catherine Halket 10. To natural son, Nicholas Berry, born of Mary Tolor, 20.". This was in addition to more substantial bequests to his four legitimate children.

Has anyone come across any of these names (Davis, Tolor (possibly Toler or Taylor) and Halket (possibly Hacket)? They would probably have lived in the vicinity of Kilbeggan.

Also, any suggestions as to which Nugent John Berry's sister (possibly Mary) was married to?
