I search Irishgenealogy.ie, a new, free, online database of Co. Kerry & Dublin church B/M/D records. I found the following:
Baptism of MARY DIGGIN of COOLHARIGILL on 1 June 1835 Parish of GLENBEIGH/GLENCAR R.C. Diocese of KERRY Name MARY DIGGIN Address COOLHARIGILL Father JOHN DIGGIN Mother JOANNA SUGHRUE Further details in the recordDate of Birth 1 June 1835 (Based on other date information) Sponsor 1 THOMAS SUGHRUE Sponsor 2 MARY CONNELL
I couldn't find an M record for John Diggin and Joanna Sughrue.
