Found an old newspaper obituary for Julia Tillou, wife of Harrison L. Tillou. Julia died Nov. 14, 1930. They were married on Jan. 3, 1861. They lived in the Spring Brook, Erie Co., New York area.
I also have a book that lists other Tillou family members, Erastus, Isaac, James and Joseph. This book was published in 1902.
Hope this will be of help.
