My family gives names of dead relatives. Jewish tradition. If not first name then the middle name. So names aren’t really becoming outdated in my family in that sense.
My 7 months old grandson has very old fashioned first name (some story behind the name but not for a relative) but a middle name is for my sons in law grandpa who passed away during my daughter’s pregnancy. Both names are very old fashioned old men names but we love it. I won’t post here but if anyone wants to know I’ll PM you hahah

And if my daughter has a baby girl (if it happens for them to have a second kid), it will be given my moms name. Very uncommon in the US. Also kind of old fashioned.
