[2] The hotel was obtained by Fulke Greville-Nugent, 1st Baron Greville when he purchased the town of Mullingar in 1858 for £120,000 (equivalent to £15,254,317 in 2023).

Algernon married Lady Beatrice Violet Graham (1842–1932) on 16 December 1863 and they had four children: Ronald (1864–1908), Camilla (1866–1938), Lilian (1869–1956) and Charles (1871–1952).

A drinking fountain monument, which originally stood on Dominick Street, was gifted to the people of Mullingar by Lord Greville in honour of his son Ronald who died in 1908, aged 43.

The figure, created using the death mask of the writer, was unveiled during the centenary celebrations on 21 March 1982 by local author and Joycean, Leo Daly.

The museum's collection includes a rare Magdalene sculpture by Antonio Canova, a collection of coins over 200 years old, a Stone Age axe dated at being over 4,000 years old, gun money, an original copy of Ulysses, a large portrait painting of Robert Rochfort showing the "great mace of Irish government" which was created in 1655 as well as a collection of items belonging to Charles Howard-Bury who owned nearby Belvedere estate.
