Thanks very much for posting this record. It looks like it--another phonetic spelling of Ballynaskeagh.
Sean Ruad's IreAtlas website shows two small townlands named Ballynaskeagh in Westmeath. One in the civil parish of Castletowndelvin and the other in the civil parish of Killagh. Perhaps they were once in the same parish.
The Ballynaskeagh in the civil parish of Killagh is just west of Craddanstown.
There is no list of townlands I can find for Catholic parishes. The last Bruton in the immediate area is a Christopher Bruton in Craddanstown in the 1911 census. The DED is Ballynaskeagh.
Thank you again.
