Timothy O'Connor/s and Mary Kean(Kane) Boolynamiscaun

I am tracing the family of Timothy O'connor and Mary Kean.

Some of their children Mary (b 1855), Bridget(b 1857), Martin (b 1859) and Ellen (b 1861) came to Australia (1886) and ssettled in Nth Queensland. Ellen married Patrick Haren 1887 Rockhampton Qld. Patrick also from Clare (Letterkelley but not sure Townland etc) and parents were Terence and Mary Hehir. Thomas, Michael , Terence brothers also came to Australia.

I am fairly sure that Boolynamiscaun is the place these O'Connors lived and were born as it is stated on Ellens history and a birth certificate that I have for her sister Ann , it is shown as "Boulinamiskaun".

My cousin is visiting Ireland next month and I am trying to help them find the family.

Where would be the place to find parish records for Boolynamiscaun or/and any other help or connection for this family please.

Thanks to all
