Dear Janet, Alice, JLynn, and Donna, Thank you all, for your advice and help. I went to a local LDS Family History Center and a VERY nice woman helped me (for several hours) to determine which microfilm rolls to order. I ended up ordering the 1860 and 1870 census rolls for Logan Co.,Ohio. And, the 1870 Montgomery Co., Ohio census roll. If anyone would like me to do a lookup for them when the rolls arrive, let me know. Thank you again, Denise
