Surname DNA testing is the newest tool available to genealogists. These tests help genealogists verify their paternal ancestry (father's father) in a quick and easy way. It saves time, prevents mistakes, and provides invaluable data that can be obtained in no other way.

 The Purpose of this Family Project is to

1. Help members of the Dieffenbach, Tieffenbach, Deffenbaugh, Devenbaugh, Tevepaugh and myriad other variant spellings to connect with their other family members around the world.

2. Determine the ancestry of Peter Deffenbaugh/Devenbaugh who died in 1805 in Allegany Co., Maryland.

3. Determine the ancestry of Johann Philip Dieffenbach who arrived in Philadelphia in 1773.
