While working on my genealogy on Ancestry.Com I found a family tree with a listing of Marsden G. Campbell of the Orleans Light Cavalry. The owner of that family tree has included all the info on my ancestor, Marsden Campbell

Since you have such great resources, I thought you might be able to answer the question: Is Marsden Campbell of Co. A, 2nd Cav and Marsden G. Campbell of Orleans Light Cav the same person?
