The second enlargement of The Hendre was under the direction of Alexander's brother John E W Rolls and was performed by architect Thomas Henry Wyatt.
The third expansion was undertaken by Alexander's nephew John Allan Rolls, the future Lord Llangattock, in 1872, again using Wyatt as architect.
On 30 March 1838, Rolls purchased his commission as a junior officer, Cornet, in the regiment of the 4th Royal Irish Dragoon Guards.
[7] The following year, on 3 May 1839, he purchased his commission as Lieutenant in the 4th Dragoon Guards,[8] and eventually reached the rank of Major.
[2][9] The London Gazette of 15 December 1848 reported that Alexander Rolls was a Captain in the Royal Monmouthshire Militia, his commission signed by the county's Lord Lieutenant.
The pump, which had a round trough at the base, stood in St James Square, previously an area of Whitecross Street.
Rolls signed an affidavit that his fiancée had married Joseph Brandon on 3 May 1855 (at age fifteen) at the Parish Church of Saint Luke, Charlton, Kent.
He also acknowledged that, on 2 June 1870, the marriage had been dissolved at Westminster, upon the petition of Joseph Brandon, with the divorce finalised on 29 February 1876.
[28][29] The marriage between Rolls and Barry (as Helen Elizabeth Brandon) was registered in the third quarter of 1877,[26] with the ceremony performed on 1 September at the Parish Church of St Mark at Regent's Park in Middlesex.
[35] Less than two years after his marriage to Barry, the London Gazette of 11 April 1879 indicated that Alexander Rolls of 82 Regent's Park Road, Middlesex County, had declared bankruptcy.
[36][37] By 1881, he was lodging in the Parish of Saint George, Hanover Square, London, and his wife was not recorded at that address.
[2][39] His widow moved to the United States following his death, where she appeared in theatrical performances in New York City.
Helen Barry's third husband Harry George Bolam (1845–1883), a land agent and mining engineer, died at Westminster Flats in New York City from pneumonia on 23 March 1883, shortly after their marriage.
