Looking for Purcell Martin and Catherine Kilkenny and Kings Ireland

Martin's and Catherine's 2 daughters, Julia and Mary came to Australia as young girls. Julia married a John Brennan and I think they went to Victoria. Julia and Mary had brothers Tobias - the eldest, I think, and Patrick, the youngest, I think also. Would love any information and contact with anyone knowing any information in regards to these ancestors.

Mary came to Queensland and married James Lewis and they had a family in Queensland, one of their daughters, Violet Catherine May Lewis - my paternal grandmother.

I am seeking any information in regard to Purcell, White (which was either James or Catherine's mother) - family left in Ireland and also for other members of the Lewis family in Queensland and Australia. have been unable to trace any.

Many thanks
