I have details of (I think) his father.
Born on 25 February 1820 in Kilrush, Co Clare, Henry Boyd was the son of a coastguard of the same name and his wife Martha. Henry junior joined the Royal Navy as a volunteer aboard HMS Victory on 7 August 1838 and was rated as a Boy (1st Class), being substantively posted to HMS Ocean at Sheerness on 1 September that year. He transferred to the Coastguard Service in Ireland, being based at Newcastle, Co Down as a Boatman from 8 March 1847. He was promoted Commissioned Boatman there on 3 January 1849. On 29 July 1851 he married Mary Ann Sullivan, the 21-year-old London-born daughter of coastguard John Sullivan, at Kilcoo Parish Church. Together they would go on to have at least seven children. Then, on 12 July 1862 he transferred as Chief Boatman to Belmullet. Boyd was finally promoted Chief-Boatman-in-Charge on 24 December 1863 and then transferred to Tyrella station in that capacity on 31 December that year. On 3 February 1869, after over 30 years service, Henry Boyd was invalided at Haulbowline Hospital. Boyd then settled in Kirkdale, Liverpool, where he now worked as a custom house officer. He lived at 48 Brazenose Road in 1871 and 7 Syren Street in 1881, at which time the family consisted of Henry (now noted as age ‘50’ and retired from the Royal Navy), Mary (45), Henry Y (24, a customs officer), Mary A (17), Simon (16, an engineer), Sam C (14, a scholar), Alice (12, a milliner) and Arthur (6, a scholar). Henry Boyd died the following year, on 12 March 1882, at home from paralysis. His son, Henry, registered his death the next day. Mary Boyd appears as a widow on the 1891 census, living with her son Samuel at 56 Syren Street (TNA ref: ADM 29/75/457; ADM 37/10129; ADM 38/991, 992, 1272, 1273, 2096; ADM 171/1, 6 and 19; ADM 175/7, 19-20, 39, 41, and 100; Newcastle Church of Ireland parish baptism records; 1871-1891 English census).
I hope this helps a little.
