Tierney1782 on Family Tree Circles

I'm looking for any info on the TIERNEY family who lived in County Westmeath, Ireland around 1782-1812. I know Michael Tierney was born 1810 to Mathew Tierney and Jane(or Joanne)HICKS born in Roscommon, Ireland. Four siblings were also born before they left to make a new life in London, England. Michael was tried in the Old Bailey in 1834 and transported to New South Wales.
Has anyone any links with research in those counties?
Many thanks
Sue Tierney
