Looking for Any Information Re Her History When Living IN County Westmeath Ireland and Her Life After Arriving IN Hobart IN 1854 on the Ship Duchess...

I am especially interested in any info re her/her families lives whilst in Westmeath, Ireland. My 3rd G Grandmother Catherine and her sister Mary worked for 5 years without spending a cent on themselves until they had sufficient funds to bring the remainder of their family to Tasmania for a better life. They were very strong women who did all they could to make their lives better for themselves and future generations.
