I am not familiar with the Ehalt you mentioned. I have recently initiated an Ehalt Web site at MyFamily.com that is for Ehalt Families Around the World. If you will email me at email@example.com
and provide your email address I can send you, or anyone else who reads this, a password and username to gain entrance into the site. I am putting everything I have ever acquired that pertains to Ehalt, Ahalt, Ehehalt, Ehahalt. So far, I have invited about 150 people sharing the Ehalt name in some way to visit and contribute to the site.
