Hi, Mary Anne,
The following from www.rootsireland.ie:
Mary Cleary baptised August 25th 1907 - Cahir - St. Maryscahir.ie - Father: Michael Cleary - Mother: Mary Loughnan,
Baptismal Sponsors: Henry Cleary and Jane Murnane
Helen Cleary baptised December 1st 1908. Father: Michael Cleary - Mother: Margaret Loughnan
Baptismal Sponsors: William Purtell and Margaret McAuley.
Address for both was Market Street, Cahir.
I have not found a marriage record for Michael Cleary and Mary Loughnan or a death record for Michael.
You should contact the Parish Secretary in Cahir - stmaryscahir.ie - to see if they have a record of their marriage and the death of Michael.
In relation to Michael Brunnock and Bridget Murphy: there are six entries: Michael 1916, Michael 1917, Michael 1918, William 1919, Bridget 1920, Bridget 1922. The duplications may be caused by death or error in transcription. You should contact the Civil Registration Office at Clonmel crs.clonmel@hse.ie should you wish to confirm those those names and birth years.
I checked for the first marriage of Michael Brunnock and found an entry of the marriage of Michael Brunnock and Margaret Flynn, Doon, Clogheen on February 27th 1900. There is a record in the Civil Registration of the death of Margaret Brunnock, 35 years Doon, Clogheen on May 16th 1911. Michael Brunnock's father is recorded as "William Brunnock", Farmer.
There are six birth enries for this "Michael Brunnock" and Margaret Flynn. 1901 William,1903 John, 1904 Thomas, 1906 Patrick, 1908 Denis, 1910 John.
I searched for a census record for Michael Cleary and Mary Cleary, but did not find any. Similar result for Mary and Helen Cleary in Cahir.
Regards,
