A slight confirmation of Knighton's account of the distress in the country parts after the plague had passed, if any were needed, is found in an inquisition made upon the death of Isabella, wife of William de Botereaux, who died upon St. James' Day, 1349. The manor held by her was at a place called Sadington, in Leicestershire, and two carucates of land are represented as lying uncultivated and waste "through the want of tenants."[258] The adjoining county of Staffordshire formed part of the diocese of Coventry and Lichfield. It comprised 165 benefices, which may form some basis on which to calculate in estimating the number of clergy who were carried off by the pestilence. Some lands in this county, near Tamworth, belonged to the Earl of Pembroke. Upon his death, whilst the heir was a minor, they were farmed out at a rent of £38 per annum, to be paid to the King. In 1351 the man who had agreed to pay that sum petitioned to have it reduced, because "the tenements with the said land so let are so deteriorated by the pestilential mortality lately raging in those parts that they do not reach their wonted value." After inquiry, his rent is reduced by £8 the year.[259] Of the two counties bordering upon Wales, Hereford and Shropshire, not much is known at this time. There can be little doubt, however, that they suffered quite as severely from the epidemic as the other counties of England. In the diocese of Hereford, including that county and a portion of Shropshire, the average number of institutions to benefices, during three years before and after the epidemic, was some 13. In 1349 there are recorded in [p142] Bishop Trileck's register no fewer than 175 institutions, and in the following year the number of 45 vacant benefices filled up, points to the fact that many livings had probably remained for some months without incumbents. This suspicion is further strengthened by the frequent appearance of the words "by lapse" in the record of institutions at this period, which shows that for six months the living had not been filled by the patron. It is probable, therefore, that in the diocese of Hereford about 200 beneficed clergy fell victims to the disease. Taking the dates of the institutions as some indication of the period when the epidemic was most severe in the diocese, it would appear that the worst time was from May to September, 1349.[260]
