Sorry, no. I have nothing on Robert & Minerva except the IGI record of the marriage. The Minerva Sutherland I found on the 1870 US Federal Census was 2 years younger than the Minerva Sutherland I found on the US Federal Census of 10 years earlier. I doubt they are the same individual at all. The events between 1860 and 1865 caused a tremendous number of individuals to be highly transient, but war always has that result.
