This article deals with merchants in international trade from the seventeenth and into the nineteenth century, most of them of immigrant background. Based on a discussion of the work of the household in gender terms the main point is to show how the merchants were eager to construct working network relations. Family and kinship relations are discussed as a crucial element in the merchants' networks, and throughout their world of household, regional contact networks and international networks run structures of hierarchical and patriarchal authority and at the same time non-hierarchical relations of equality.
