His great-grandfather was Alexander Brown, the founder of Alex. Brown & Sons, the first investment bank in the United States. Among his extended family was grand-uncle George Brown, founder of Brown Bros. & Co. and Baltimore and Ohio Railroad, and uncle John Crosby Brown, who became the senior partner in Brown Bros. & Co.
