  General Notes:

Hankins (Hamilton's 1980 biographer) mentions in his Acknowledgements that John O'Regan (Hamilton's grandson) and Phoebe Alice Abbott O'Regan had (in any case) two sons: John W.H. O'Regan and Michael L.V.R.H. O'Regan. No more data is given about them.

from A. van Weerden <a.vanweerden-AT-uu.nl>
I found birthdates of the three sons of Hamilton's grandson John Rowan Hamilton O'Regan, they were named in a 1987 book by Wayman: Dunsink Observatory 1785-1985. He gave the dates:

John William Hamilton O'Regan: 1913
Michael Lionel Victor Rowan Hamilton O'Regan: 1916 Patrick Valentine William Rowan Hamilton O'Regan: 1920

I found their complete names in:
T. R. Dawson
The Mathematical Gazette
Vol. 24, No. 261 (Oct., 1940), pp. 291-294 The screenshot is p. 294.
