Most estimates for numbers of Roma victims of the Holocaust fall between 200,000 and 500,000, although figures ranging between 90,000 and 4 million have been proposed. Lower estimates do not include those killed in all Axis-controlled countries. A detailed study by the late Sybil Milton, formerly senior historian at the US Holocaust Memorial Museum gave a figure of at least a minimum of 220,000, probably higher, possibly closer to 500,000 (cited in Re. Holocaust Victim Assets Litigation (Swiss Banks) Special Master's Proposals, September 11, 2000). Ian Hancock, Director of the Program of Romani Studies and the Romani Archives and Documentation Center at the University of Texas at Austin, argues in favour of a higher figure of between 500,000 and 1,500,000 in his 2004 article, Romanies and the Holocaust: A Reevaluation and an Overview as published in Stone, D. (ed.) (2004) The Historiography of the Holocaust. Palgrave, Basingstoke and New York.
