The movement of trow crews up and down the Severn (and Wye) is a fascinating subject for further research, including linkages in family history. If anybody looking into this subject comes across the name Sterry, Sterrey or similar, please post. There is a suspicion that this surname, frequently found in and around Lydney/Awre/Westbury/Minsterworth for some 250 years, and for much longer around Longhope and Ruardean, may have floated up and downstream.
