Looking for info on Clyne sisters from 1880's

Greetings from Australia,

I am seeking info on my Greatgrandmother, Annie Olive Clyne and her sister Mary Clyne. Both were born (of Edward Clyne and Ellen Moran) in Mohill, Leitrim in 1868 and 1863 respectively. (Annie may have been born in township of Drummond - according to unreliable info). All info according to death certificates.

Annie is believed to have arrived in Queensland in 1884 and then NSW two years later. Married George A Holden in 1890 in Balmain, Sydney.

Mary Clyne arrived before Annie but no reliable records. Married Henry Nichols in 1890 in Forest Lodge (Glebe area), Sydney.

Both women may have travelled to Australia on un-assisted passage but there are no accurate records of their voyages. They are both died reasonably early (at 56 and 46 respect.) but were mothers of healthy clans of Holden and Nichols children.

Any information on Mohill (or Drummond/Dromod?) birth records would be appreciated. Also cannot locate any other decendants of Edward and Ellen Clyne from 1901 Census etc.

I would love to also gain any info about Henry Nichols who may have come from the same area. Given that Mary Clyne arrived at age 19 but then married Henry at 24/25, they may not have know each other before meeting in Sydney.

Many thanks for any clues or tips or family info...
