I had proposed a merge of Lauterback-10 and Louderback-26, leaving the following instructions for whoever ended up being able to actually complete the merge: "Louderback is more consistent with other members of the family and their descendants. Laauterback is closer to father's name in Germany, but Louderback is the Americanized name which would have been used by someone born in North America."
When the merge was completed (surprisingly by someone who is not one of the profile managers), she chose to override my reasoning with the following comment: "Lauterback is the correct Last Name at Birth although both variations are correct. Went with Father's LNAB".
The father's will bears his mark. He was illiterate. How did he spell his last name? He didn't. In the few cases that the name of any member of this family was reduced to writing, it would have been written however whoever was recording it decided it should be spelled. If the father's German name included diacritics, it would probably be clear that a daughter born in America would have an Americanized name.
None of her siblings have a LNAB of Lauterback. Most are Louderback. Wouldn't more consistency in naming make it easier for later researchers to see these siblings as related?
One of the defining features of a wiki is that anyone's additions can be backed out, but in the case of a merge, that doesn't seem true.
