Looking for Delany and Browne ancesters

I'm looking for ancesters of my grandfather Vincent Gabrial DELANY.  On 3 May 1868 he was born in Tuam 1, Galway.

His parents are Mary Ann Victoria BROWNE and Thomas DELANY.  I have a marriage entry from "Ireland Select Marriages 1619 - 1898".  The Index entry reports Mary and Thomas were married in the District of Luans, Co Galway on 24 April 1867.  It records Marys father as Michael Joseph BROWNE and Thomas's father as Thomas DELANY.

Anything further back on the DELANY and BROWNE familly would be fantastic.

My grandfather Vincent DELANY married Elizabeth Mary Josephine Hassett on 5 August 1893 in the Church of St Marys Rathkeale.  Elizabeth was from Rathkeale.  Vincents father is recorded as Thomas DELANY and Elizabeths father recorded as James HASSETT (his wifes name is Mary McNamara).  Elizabeth has siblings, all born in Rathkeale, Patrick born 26 Sept 1866, Mary Ellen born 16 Mar 1868, Michael John born 9 August 1869 and Mary Ellen (poss - not confirmed) born 21 November 1873.

Anything on all of the above would be most appreciated.

Many thankyous
