I believe that there was a general agricultural depression in
England during the second half of the 19th century. My mother's family were ag labs in Cambridgeshire, again East Anglia, relatives of my father lived in South Lincolnshire, again near enough. Many of my mother's relatives moved north, to industrial Teeside, her uncle moved to Australia, and an uncle of my father from Pinchbeck South Lincs. moved to Canada, he returned 20 years later, complete with bride!
