Benjamin was among the youngest of the numerous children born to Marks and Richa Lazarus. Among the older siblings that he had to look up to during his Charleston childhood were Emma and Joshua. His middle name— Dores— is a testament to his Sephardic heritage and to the process of acculturation: it condenses the Spanish "De Torres." His father was a middleclass shopkeeper. He had served during the Revolutionary War, eventually achieving the rank of major, in Lushington's company— known as Jews' company for their prevalence within its ranks.
In 1840 he married his niece, Cornelia Cohen, daughter of his sister Leah Lazarus Cohen and a wealthy Polish peddler-turned-planter Mordecai Cohen. The couple remained in Charleston and had six children. [4]
