rparker on Family Tree Circles

My grandfather Robert Otto Parker was born in 1888 in Rockport Indiana and his father was E.M. (Emory Morton)Parker born in 1860's also in Indiana. I have obtained my granfather's death certificate which listed his father as E.M. Parker but I cannot find much more than that.

Robert was married to Sudie Hazel Johnson from Kentucky and they had 5 children Robert Jr., Richard, Raymond, Joanne and Linda.

E.M. Parker was married to Elnora Higgins from Indiana.

Anyone with more information would be greatly appreciated
