Hi, I've researched my Rogers family in La Salle and Grundy counties. The Morman Church has, at their Family History Centers, many film that can be ordered from Salt Lake City. Two that I found especially helpful were: Grundy Co. vital records, film # 1,415,755 and La Salle Co. mariage record index, film # 1,710,810. They have others that might be just as helpful. Good luck. Dorothy
