The Harbaughs and Wagamans of Harbaugh Valley,MD

I am a beginning researcher looking for connections to the German immigrants who settled in and around the part of Frederick County known as the Harbaugh Valley. My interest began
in 1995 with a Harbaugh Family Reunion. It continued with a
2000 reunion and looking forward to one in 2005 to be held in
the Harbaugh Valley area. As I look at all the work of true geneologists, I realize that there is much to be done and walls
to be broken through. Thanks in advance for sharing.
