Mary KilKelly and Patrick Carr

My grandfather Patrick Carr was born March 1865.  He was baptised in the Parish of Ballymacward and Clonkeen Kerrill,  Diocese of Confert.  I have found his baptism in the parish register.  I have also found him in the Births registered in the District of Athenry in the Union of Loughrea in the County of Galway.  This record states his father as Patrick Carr, Gurteen, Farmer;his mother Mary Carr formerly Kilkelly:  witness Bridget Carr  sister Gurteen.  

I have not been able to find any marriage or birth records for his parents:  Patrick Carr and Mary Kilkelly.  I have also not been able to find any birth or baptism records for Patrick's (1865) siblings.  Katherine (abt 1852), James (1859), Nora or Hanora (1862) and Mary (1864).

There is a family note that reads:  Grandfather Carr, County Galway; Town - Athenry, Tuam - Gurteen

Kil-Kelly maiden name of great grandmother.  This note was written by Patrick (1865) daughter (my aunt).

Any help finding Mary KilKelly or Patrick Carr will be greatly appreciated.  Their son Patrick (1865) came to the US.  Settled in Waltham, Massachusetts and had 9 children.
