Mrs Edward Mack (Mary Ann Lacey) was born in Harborne, Staffordshire, England in late 1854/early 1855. She was baptised in her village on 7 January 1855.

She was the daughter of George Lacey (b. 1828 in Edgbaston, Warwickshire), a coachman, and Mary Every (b. 1822 in Bewdley, Worcestershire) who had been married in Birmingham on 14 March 1852. Her six known siblings were: John (b. 1854), Emma Maria (b. 1856), Harry (b. 1857), Elizabeth Agnes (b. 1859), Mary Amy (b. 1861) and Edith (b. 1863).

Mary first appears on the 1861 census living at Park Lane in Harborne but her whereabouts over the following years are difficult to trace as she and several of her siblings are not listed with her parents. Her parents eventually settled in Hove, Sussex and her mother would die in early 1882 with her father remarrying to a London-born woman named Annie Maria Harton (b. 1833). He would die in 1899 and his widow the following year. 

Mary was married in 1875 to John Arber and their daughter Agnes Mary was born in Marsden, Surrey on 12 August 1877. Young Agnes appeared living with her grandparents George and Mary Lacy on the 1881 census at 10 Brunswick Street, Hove, Sussex. Mary herself was listed as a visitor at 6 Spear Mews, Kensington, London and described herself as an unmarried domestic servant. What became of John Arber is not clear; whether he died or just became estranged from Mary is not certain but it would seem that they were just living apart.

Mary became involved with another man, Edward Mack (b. 1841), a bookmaker commission agent, although it is not clear if they were ever officially married. She appears on the 1901 census living alone at 7 Wimpson (?) Lane, Millbrook, Hampshire and she and Edward are together on the 1911 census living at 46 Clarendon Road, Shirley Hampshire. Edward died in early 1912 and was buried on 27 February that year.

Her daughter Agnes had been married in 1901 to Bernard Joseph Haran (b. 14 April 1876), a native of Liverpool, and their son Frank Lacey had been born on 20 January the year previous. They later emigrated and by 1912 lived at 446 West 55th Street, Manhattan.

Travelling from her home in Southampton, Mrs Mack boarded the Titanic at Southampton as a second class passenger (ticket number S.O./P.P. 3, which cost £10, 10s)¹. She was en route to her daughter in Manhattan.

During the voyage Mrs Mack shared a table in the saloon with Benjamin Hart and his family and Thomas Brown and his family, among others.

Mrs Mack died in the sinking. Her body was recovered by the MacKay Bennett and was buried at sea on 22 April 1912.

In June 1912 Agnes Haran received the effects of her mother found on her body.

[Case no 286]
(English). An aged English woman was drowned while coming to this country, after the recent death of her husband, to make her home with her only daughter. The daughter's husband, a waiter, at the time of the disaster was recovering from a severe attack of typhoid fever. The mother's body was recovered, and this Committee provided funeral expenses. Later, it was learned that the body had been buried at sea. The mother was bringing her household goods, a large amount of clothing and some cash, the exact amount of which is unknown, and, in view of this property loss, the daughter was permitted to keep the appropriation.

Mary's daughter Agnes would later suffer the loss of her son Frank on 16 October 1926 aged 26. Frank, a chauffeur, had only been married two years previous, to Helena Fox (b. 1900 in Co Roscommon, Ireland). Agnes lived at 1670 Lexington Avenue, Manhattan up until her death on 12 June 1932. She was buried in St Raymond's Cemetery.

Her widower Bernard, a club waiter, was remarried the year after his wife's death. His new bride, Rose Edna Caffrey (b. 1887 in Ireland), had been in his life for some time and had been listed as living with him on the 1930 census as a servant (his wife at the time being conspicuously absent). Bernard's second marriage was all too brief and he was made a widower after less than two months of marriage. He remained in Manhattan and died on 14 February 1944, also being buried in St Raymond's Cemetery.
