Couples who stopped cohabiting when they were unable to resolve their marital difficulties became part of a sizeable minority of individuals who lived outside a marital relationship in the later seventeenth and eighteenth centuries. Early in this period 15% of adults never married, though their numbers had declined to 7% by the nineteenth century. Frequent widowhood forced many others to live without a spouse for a period of time, and it became less likely for the widowed to remarry by the later eighteenth century. The numbers of separated spouses joining these groups are difficult to estimate. Pamela Sharpe concludes that 10% of marriages that took place in Colyton, Devon, between 1725 and 1756 ended in separation, but detailed parish reconstitutions of this nature are few and far between. Studies have also counted the numbers of desertions found in the material generated by the settlement laws. Yet this is no indication of total desertion rates within a population, never mind separations not caused by absconding husbands. In general, the types of records which contain information about marriages ending in separation and/or desertion neither are directly comparable nor do they reflect the total incidence of temporary and permanent separations. Though it is impossible to count separated spouses, the records of marital difficulties provide valuable information about the circumstances leading to marriage collapse and the living and working arrangements of spouses thereafter.
