Max, it is difficult to find official records online after the 1901 census, apart from indexes and directories.
Someone else was asking about Ramsey records a couple of months ago, and I suggested two books by Constance Radcliffe called 'Ramsey 1600 - 1800' which has maps and photos, landowners, seafarers, the port and shipping, the school, the Chapel, etc., and 'Shining By the Sea, a History of Ramsey 1800-1914' which I haven't seen. The first book has several pages about the schools, including the early days of the Grammar School.
You should be able to buy them second-hand - try www.abebooks.com/ which is a reliable website, but check first with the bookseller - and be quick!
