An Austrian woman married an English man by Licence at St. Thomas Register Office in August 1911. Would this marriage have automatically given her UK citizenship? If not, when World War 1 started, what would have been her position as an apparent "alien" of a country we were at war with in 1914. (incidentally by which time the couple had already had 2 children - one born in Devon and one born in Somerset)?.

Thanks, David
