The idea of grandparents names has shifted. Time marches on, cruelly!
In my day, Grandparent Names were things from the 30s and early 40s, because that's when *my* grandparents were born. Stuff like:
ShirleyHelenMarthaDorothyRuthBarbaraSandraCecileRoseMarilynJoanBetty (rarely
Elizabeth; usually
Betty in full)
FrankWalterGeraldEugeneArthurCarlNormanHaroldAlbertAlfred
But now, grandparent names are probably more of what I thought of as "mom and dad" names - things from the 50s, 60s, maybe even the 70s. Stuff like:
Lori (so many of my friends had moms named
Lori,
Laurie, or
Lorraine)
ElaineShelleyAnitaSharonKimberly (
Kim)
DonnaDianeCynthia (
Cindy)
LindaSusanDeborah (
Debbie,
Deb)
Janet and
JaniceBarryGaryLawrence (
Larry)
BryanGregory (
Greg)
Ronald (
Ron)
Douglas (
Doug)
Jerome (
Jerry)
(this is the era of "buddy" names. Everyone has a name that makes them sound like someone's buddy or pal that lives down the street)
Stuff like
Gertrude and
Bertha are beyond grandparent names. They were the "grandma" names to my grandma, probably.
