William Browster IN Nsw Australia

Do you recognise William Browster died 26 November 1864, intestate?

"18 January 1866 this day upon Petition administration of all and singular the goods chattels credit and affects of William Browster deceased granted to Elizabeth Carbuss the Mother and next of kin of the deceased intestate. Intestate died 26 November 1864 Goods sworn at 15pounds. Letters of Admon date the same day as paid"

I am hoping to find out more information his mother Elizabeth Carbuss/Carbiss who may have been married to a Mr Browster, the father of William Browster

On her marriage certificate to William Carbis in 1847 she was known as "Elizabeth Clarke"

Hoping someone can help.
