Greetings,
I am seeking any CW service records for Alexander B. Wilson, born 1838 in Greene county TN. I find the following census and NPS data, but don't know which or any of the NPS listings are my man. Thanks very much for any assistance. I have family serving on both sides, but have no knowledge on this particular ancestor.
