Educated at Elizabeth College, Guernsey?
How do we know these people were educated at Elizabeth College, Guernsey? Shouldn't each article about a person mention that they were educated at Elizabeth College, Guernsey, with an inline citation? Some articles do not have any mention of Guernsey at all, except for this category, such as Lewis Halliday.--Dthomsen8 (talk) 22:10, 30 October 2018 (UTC)
