Earl Roger and his associates added several estates and other sources of income to Shrewsbury Abbey's endowment, which had been valued at £46 18s. in 1086, before the first abbot was appointed. As well as rural manors, the abbey had urban property, mills, and the tithes and advowsons of many churches. However, Orderic, a shrewd observer, tells us that Roger only "moderately endowed with lands and rents" ("terris ac redditibus mediocriter locupletavit"). Moreover, there was a long wait ahead before some of the endowments were to materialise.
