It is not possible though to prove lines because of the a relationship between different family similarity of the coats of arms, since the idea to create a "telling coat of arms" for this name is a very obvious one. All this leads to the conclusion that comparisons of the forms of the name or the coats of arms are no help in. Finding connections between different lines of the family. When after the war (WW I) and the inflation the question of family reunions appeared, there was no doubt that who belonged to the family or not. From the beginning it was clear that all the descendants of the ancestor Johnann Georg Haeberlen were invited as well as their dependents.

The consciousness of belonging to the same family and the sense for blood relationship was not equally strong in all members of the family, naturally stronger in the older ones than in the younger ones. That the cultivation of family bonds is not only a vain hobby but also serves to strengthen ethnic bonds, that is a conviction which is getting stronger and stronger in our (national-socialist) days. But this idea has always been very lively among our relatives.

Above all the head of the so called Gaildorf line has to be mentioned: court-notary August Haeberlen (VIII,3), whose research gave us the first family tree in 18.65. For a long time this important document had not been known in the family, but then his son, the above mentioned Karl Haeberlen (IX,18) spread it among other family members.
