This couple married before 1843,possibly in Aberdeenshire. I am looking for information about their sons James (1845), John (1847), William (1854), Joseph(ca 1857) and Robert(ca 1860). Did James marry? Who was John's first wife, before Isabella Silver? William married Agnes Horsburgh and went to South Africa. When and where did he die? Who was Joseph's wife and where did he live? Did Robert die young?
