That makes sense. According to the Virginia Tech Department of Music on-line dictionary:
"The English horn is the direct descendent of the oboe da caccia, which was used through out the Baroque period. There is some debate on the name English horn, because the instrument is neither English nor does it look anything like a horn. The reasoning of this could be, because the English horn used to be called the cor angle since it had a bent shape similar to some of the older instruments. Angle, which is a French word, was mistranslated as anglais, or English. Even with the modern instrument being straight, the translation is still used and the instrument is still known to this day as the English horn. The English horn, or the oboe da caccia, was often used in Baroque music, but was not used very much from Haydn's time to Wagner's era. In the works of Berlioz and Meyerbeer the English horn received attention. Starting from the middle of the nineteenth century on, the English horn has had a more prominent position within orchestral music."
