Norman, If it helps I have him on the 1851 census. In the Ancestry index he is ROWEROFT but the image is fairly clearly ROWCROFT and someone has submitted a correction to Ancestry . Maybe someone else has him on their submitted Ancestry tree. He was a widower, calico printer and he was in the workhouse as a "patient" rather than a "pauper". There is nothing else on the image other than what you already have. Do you want me to look him up in 1841? Eric Millward.
