Hello Jean: No, marriage records such as you want are not online. $7 will get you a certified copy from the County Clerk, Rm 101 Courthouse, 324 Main St., Peoria, IL 61602. Tell them the date (at least the year), names of bride and groom, WHICH record you want (in this case Marriage), number of copies, and what your relationship to them is. Sign and send the request along with the $7 cash, money order or bank draft (they do not accept personal checks!!) Bill in Denver
