McManus/McDonald Killinkere /Cavan

Hello,

I'm after some information on my great great great grandparents Terence McManus and Rose McDonald who were possibly born in Lissanymore in 1816 and 1818/9 respectively.They married in Lissanymore in 1841 and emigrated to South Australia in 1854 with their 6 children. Does anyone know of the names of their parents or siblings and their occupations or any other relevant facts?

Thank you so much for any help,
