There are some remarkable coincidences here.
In the 1911 census, there was a Nora O'Regan aged 29 in Sixmilebridge and a Nora O'Regan aged 28 in Labasheeda.
The Nora O'Regan in Sixmilebridge had been married for two years with one child born, one child still living (Mary Rose, aged 1). She was one of five people in her mother-in-law's all-female household. Her husband was not with her on census night. See

There was no James O'Regan in all of Clare.
There was a Clare-born James O'Regan, merchant and farmer, enumerated in Dublin, staying with his recently-married sister Delia and her husband Patrick Quinn. See

R.I.C. men were generally enumerated by their initials only, so it should not be a big surprise that I cannot find James O'Regan of the R.I.C. in a first quick look in the census.

There is lots more about the family of James O'Regan and Nora Ryan of Sixmilebridge at
http://www.clarelibrary.ie/eolas/clarem ... tion/1.htm
That Nora O'Regan née Ryan was the daughter of Andrew Ryan and Jane Kelly of Kilrush. Her widowed sister-in-law, another Nora Ryan (née Kennedy) married secondly on April 20, 1949 to my second cousin once removed, Timmy Sheehan of Kilrush. I have lots more information on the Ryans of Kilrush
Unfortunately, I have no information at all on the other Nora O'Regan née Ryan(?) mother of Dermott/Dermod O'Regan.
The R.I.C. records are available at ancestry.com. There is only one James O'Regan included, namely James Thomas O'Regan who enlisted in the Irish Constabulary, as it then was, in 1858, aged 19. He would have been over seventy years of age by the time of the 1911 census.
