Several years ago, Arphax Publishing Co. popped into the genealogical spotlight with its historical land ownership maps. ...
The original Arphax product was a series of "Family Maps" of individual counties showing original purchasers of land indexed through the U.S. Bureau of Land Management or the Texas General Land Office.
This month, the collection will go digital at HistoryGeo (www.historygeo.com) with a subscirption model. There seem to be maps in about 40 US states.
