Martin met his future wife,
Cornelia Sherman (1843–1920), at the wedding of
Emily Vanderbilt, second daughter of
William H. Vanderbilt, to William Sloane, where she was one of Vanderbilt's bridesmaids. The couple courted, were soon engaged, and were married about a year later. Cornelia was the only child and heir of Isaac Sherman (d. 1881), a retired merchant who lived on West Twentieth Street in New York and was close friends with
Abraham Lincoln. Together, they were the parents of three children: • Sherman Martin (1869–1894), who died aged 25 in New York of
apoplexy, but rumors at the time indicated it was suicide. He was married to Annie Nunn, an English girl. • Bradley Martin, Jr. (1873–1963), who married Helen Margaret Phipps (1876–1934), a daughter of
Henry Phipps, Jr., in 1904. •
Cornelia Martin (1877–1961), who married
William Craven, 4th Earl of Craven (1868–1921), son of
George Craven, 3rd Earl of Craven and grandson of
George Barrington, 7th Viscount Barrington, in 1893. Martin died of
influenza, which developed into
pneumonia, on February 5, 1913, in
London, England. At his death, his New York estate was valued at $1,277,341. The foreign estate was not valued as Martin took up permanent residence in England in 1899. His widow died at her country residence at
Hamstead Marshall, England on October 24, 1920.
