Not had a chance to properly go over this yet, but Ancestry has jusst added a VC database to its military collection. That's a good thing of course, although VCs are a well researched topic and there probably won't be anything new here for anybody.
Unfortunately the collection, such as it is, is only browsable by surname letter, and the quality of the images leaves much to be desired. My recommendation: Google your VC hero first and scoop up all the free stuff that'a already on line. You'll probably end up with as much, if not more, than there is on the Ancestry VC collection.
