The Muster Roll of the province of Ulster is a large, leather-bound volume in the British Library. The volume consists of 283 folio sheets on which are recorded the names of 13,147 males from the nine counties of Ulster. Each county forms a separate section of the volume and the men who mustered are listed under the names of their landlords; beside each man's name is a description of the weapons he was carrying or a note that he was unarmed. Most of the men who mustered were English and Scottish settlers and, in the absence of comprehensive parish and estate records, the muster rolls is the nearest one has to a census of the British population of early seventeenth-century Ulster. This edition includes much supplementary information on the settlers, drawn from numerous contemporary sources.
Men and Arms: The Ulster Settlers, c. 1630 contains all the c. 13,000 names in the Ulster muster roll. In addition, and this is where Bob Hunter's and John Johnston's scholarship has added considerable value to the document, they have also appended information on these men in the muster rolls from sources such as the 1622 commission survey and the depositions following the 1641 native rising. This information is made available as extensive footnotes to the original muster roll listings.
