Anne Cashin born 1822

Hello,

My great great grandmother was Anne Cashin of Coolnakisha, Tullowcreen born 1822 to Patrick Cashin and Anne Daly. She married Thomas Cummins in Leighlinbridge Co Carlow on 10 July 1853. Within a couple of months Anne and Thomas left Ireland by Ship via Southhampton for South Australia landing in December 1853.

I am still looking for any records that show from where Thomas Cummins (B. about 1815) and his family originated. 

I would be very interested to know any information about the Cashin family at that time. Or any information on who Thomas Cummins might have been. Cheers. Mark.
