Hi Mary, Welcome to Ireland Reaching Out.
I have had a look at trying to source records for Hugh or Bridget Carroll, that emigrated to Australia, back in the 1850’s but I don’t seem to be having much luck with this so far. I have shelved this for the moment to see if maybe I can help you try to connect to any Carroll family that would still be living on Tory Island or living in Parishes nearby.
Tory Island can be found in the Parish of Tullaghobegley in North-West Co.Donegal. I have attached a link below that will take you to that Parish Page on Irelandxo.com - https://www.irelandxo.com/ireland/donegal/tullaghobegly
Within this Parish Page you will find an article created for Donegal Genealogy Website (Parish of Tullaghobegley), this will give you access to a wealth of Knowledge available for the Tullaghobegley locality.
As regards Carroll families there were two families living on the Island of Tory at the start of the 20th century. One of these was a James Carroll and the other was a John Carroll, who was possibly a brother.
This is James Carrolls family in 1901 and 1911
1901 Census Ireland - James Carroll Family on Tory Island
1911 Census Ireland - James Carroll Family on Tory Island
And this would be John Carroll family in 1901 and 1911
1901 Census Ireland - John James Carroll Family on Tory Island
1911 Census Ireland - John James Carroll Family on Tory Island
I attached a photo of a Carroll Family Tree I put together, just to display these two families and how they would possibly be related to Hugh, Bridget and Anne carroll. Tory Island is a small community so it wouldn’t be hard to see how they would have been related.
I used https://civilrecords.irishgenealogy.ie/, to see what records I could source for the children. Given time there are loads to be sourced. I came across a marriage record for Sarah Carroll who would have been was a daughter of James Carroll and a Birth record for Owen Carroll who would have been a son of John’s (below).
SARAH CARROLL, marriage to EDWARD MCCLAFFERTY
Marriage: 26 October 1914 – Tory Island

I will ask to get this Message attached to the Tullaghobegly page, as this will increase the chances of making a family connection. If you have a copy of the Missing Friends advertisement that was placed in the Australian Journal back in 1888, that would be worth adding here. The best recommendation I could give going forward is to keep gathering as much information as can be found on Carroll families in Tory and reach out and share it politely on the one or two facebook pages available for Tory Island. What do you think Mary.
Kind Regards
