Familienforschung, Genealogy, helping hand

In light of my gratitude towards Herr Kregel  and his big genealogy gesture in obtaining information.His help was very valuable forerunner in what I know today.  I have no idea if this is his family or even him, but I like the website so I thought I would share it  so it won't get lost in the shuffle.
