Between the1880's and 1920's in part of Galicia that is now Poland, Jewish marriages were not legally recognized. This resulted in inconsistent birth records - for the same parents, some have the mother's last name, some have both mother and father last names, and some have father's last name.
What adds an order of magnitude to the mess is that I'm working on a family with 18 children (same father but 3 different mothers). In all cases, the children used the father's last name throughout their lives. I found one record (so far) indicating the name had been legally changed to the father's last name. That person's kids are another mess - some registered with his wife's last name, some with his father's last name and some with his mother's last name (from before he made the legal change).
Please also be aware that I have only been able to find birth records for 11 of these 18 children, so there's also a question of what LNAB to use for the other 7.
I had started adding profiles, using the father's LNAB, before discovering all this, so if the answer is to use anything other than the father's LNAB, it will mean some LNAB changes.
On top of all that, there are spelling variants in the mix. The father's name is Honig, but records show Honig, Honek, Honik, and maybe a few others. Two of the mothers were sisters - their LNAB is Fallek, Falek, or Falak. Even the father's mother's LNAB gets into the act - it's Gris or Gries or Griess.
I'm tempted to forget the entire mess and just use the father's LNAB for everyone - that's what all the family members always did, but then there are those pesky official records that I suppose we're supposed to be going by.
What's a beleaguered WikiTreer to do???????
NOTE - linked profile is the father. None of the mothers have been added yet, but they are all mentioned in the father's bio. Not all of the children (also mentioned in the father's bio) have been added yet, either, but I'm working on it … check back in a few million years or so when I'm finished with this family!
