There are 4 George MILLERs in the 1870 Wood Co. census index: Troy Twp.pg.544, Troy Twp.pg.553, Middleton Twp.pg.392, and Plain Twp.pg.520. There is no Roger PARKE or PARKS, but there is a Rayss PARKE in Weston Twp.pg.589, which you might want to check on- it's often difficult to interpret the census taker's handwriting. Roger PARKE is named as the father-in-law of H.B PIKE (a resident of Weston Twp.) in the 1875 Atlas of Wood Co. The exact wording is: He [H.B. PIKE] was married to a daughter of Roger and Hannah Parke, who removed from Putman [sic] County, Ohio, into Wood County in 1869. Their family consisted of sons and daughters, as follows: Martin T., Mary J., George (deceased), John C., James D., Ella, Thornton (deceased), Margaret, William D., Edward E., and Frank (deceased).
