Starke,

I would be interested to see what you have on Constantine Chapter member Reuben T. Pollard, Mississippi 1861.

The Sigma Chi national fraternity may have some of his biographical information, but if they do not, I'm sure they would be interested in what you have uncovered. http://www2.sigmachi.org/resources_hq/contact_list.phtml
