Strictly speaking although Victoria was born into the House of Hanover, they only recognised male heirs, so she lost the title (which was Elector of Hanover) when she became queen in 1837. Edward VII took her family name from her marriage to Albert. So he is from the House of Saxe-Coburg-Gotha. As a result of World War I (Edward died in 1910) anti-German feeling caused George VI to rename the family name and he chose Windsor. Thus the Windsors rule today, but are really directly descended from Victoria and Albert.
