I checked the Somme online archives-you can find them here. Y has decennial tables but unfortunately only begins offering scans of the acts themselves starting in 1839. Curiously, there is a death listed for a Jean Baptiste Huiocq on 20 March 1828.
The spelling of the last name is similar to Gallicized versions of the Germanic language family surnames Hook, Hoock, etc. that I've encountered previously in researching my Belgian ancestors. I also found a child with the same surname (possibly Céline as the given name, it's hard to read), who was born on 21 October 1827 in Y.
