Atkinson Family History Yorkshire UK

I am researching our Atkinson family history and particularly interested to find out if any more of our family came to Australia.
My husband's father Thomas Albert Atkinson & his brother George Robson Atkinson both came out to Australia in the first part of the 1900s (believe Thomas on the "Limerick"& George on the Örvieto")
Father of the boys was Thomas Atkinson (dob 1860) and mother Elizabeth Isabella Holliday
All the children were:
Herbert - 1886
Ada Elizabeth - 1888
George Robson - 1890
Edith May - 1894
Ernest Walter - 1896
Arthur G. - 1897
Louisa (Louie) - 1898
Isabella - 1900

All were born in Yorkshire UK.
Other possible information is that Thomas 1860s Father was George married Isabella Jackson
