I will have to see if there is anything for Hancock County on FHC film that we havent tried -- also the Illinois Newspaper project lists some few reels for Hancock County papers of the time that I would not mind looking through page by page at all , if it would get us somewhere.

Children of Michael and Christina Bock Courtney in order and some few corrections to your list:
Edward Leo b 1888 (Became Father Henry Courtney OSB)
Clement Francis b 1890
Clara Christina b 1891
Otilia Ann b 1894 (became Sister M Raymond CSJ)
Louis Raymond b 1896
Charles b 1897
Josephine b 1899
Gerald Joseph b 1901
Justin b 1903
Mary b 1904 became Sister M Ancilla
Genevieve b 1907 became Sister Genevieve Clare
Wlliam b 1908

That's all 12 of them, think you had Gerald 2x in your list and missed a couple the others. The young orphan Michael Courtney became a grocer and had this whole big family of his own - not very much contact with his siblings over the years, but sometimes.
