I also recently found that 1851 Census and it is a very good possibility but I compared the 1861 census you attached with the one I have for Alexander, Donald and Sarah in West Williams, Middlesex and now I have a mystery. It appears to be the SAME census for same area, same neighbours, etc... but mine has “absent family members” Neil and Anne missing altogether! Having Neil (listed as soldier, residence unknown) and Anne (residence London) is a game changer as I recently had one researcher in Scotland find a 1841 Scotland census for John, Marion, Christy, Neil, Donald, Ketty, Anne. No Alexander as MonicaL said though but the best lead yet! Birth years close and living in Benbecula, South Uist. I have attached the 1861 census in question. Let me know what you think...
