She was born in what was called Prussia in 1860 and died in England in March 1917, from influenza (the great pandemic occurred in 1918). The world had changed - she married into the Welf-Wettins in 1879 when a Welf-Wettin was Crown Princess of Prussia. In March 1917, the outcome of World War I was very much anybody's guess, the Hohenzollerns were in jeopardy, and the Welf-Wettins had re-named themselves the Windsors. Connacht (anglicised to Connaught) is located on Ireland's west coast and contains Counties Galway, Leitrim, Mayo, Roscommon, and Sligo. Her Wikipedia article is here.
She married Queen Victoria's son Prince Arthur in March 1879. Her wedding dress is a timeless classic, like those Princesses Alexandra, Beatrice, Mary (May of Teck), Grace, or Margaret (Margaret Rose Windsor). Her mother was Princess Marie of Saxe-Weimar-Eisenach.
