Recent work on white women in Jamaica has shown that they were active participants in Jamaica’s slave economy. This article adds to this recent literature through an innovative use of social network analysis (SNA) to examine the credit networks in which women operated in the thriving eighteenth-century British Atlantic town of Kingston, Jamaica. In particular, it uses closeness and centrality measures to quantify the distinctive role that white women had in local credit networks. These were different from those of men involved in transatlantic trade, but were vital in facilitating female access to credit enabling domestic retail trade. White female traders in particular facilitated female access to credit networks, acting as significant conduits of money and information in ways that were crucial to the local economy. Their connectedness within trade networks increased over time, despite their greater exposure than larger traders to economic shocks. We therefore demonstrate that white women were active protagonists in the developing economy of eighteenth-century Jamaica.
