My sister and I have nice Biblical names...Rachel (me) and Rebecca. They've kind of maintained popularity so they are older names that don't sound "old." (My middle name is Irene...that isn't old!)
I was born in the 70s and it seemed like every third girl in school was named Jennifer. When I competed in my local Junior Miss program, out of sixteen contestants, four were named Jennifer. No wonder that name isn't so popular for babies now. heh.
Hootie: I went to school (grade school-high school) with a Lorraine. So that name doesn't seem super old to me.
I would never name my kids things like Gertrude or Ethel or Edna or Bertha. Nor would I name them things like Makayla or Mackenzie or anything like that either.
