Does anyone have information about John Porterfield and Amelia Brown? They had a son, Robert L. Porterfield, born about 1853 in Illinois.He married Eliza S. Pugh on 31 Jan 1884 in Mahaska County, Iowa. They had three children: 1. one was stillborn; 2. Sidney E. Porterfield (1886); and 3. Peter C. Porterfield (1889).
The last place that I found Robert & Eliza Porterfield were in Mahaska County, Iowa, 1910 census.
