I remember all four grandparents, but I didn’t know my father’s parents very well because they lived in Germany and we didn’t share a language.
My mother’s father died first, when I was 13, and my father’s mother died last, when I was 34.
I do miss them all, though part of what I’m missing is my own childhood, surely.
My paternal grandfather died before I was a year old
Next to go was my maternal grandfather who died when I was about 4 or 5. I can very faintly remember him, but He was basically bedridden by strokes when I knew him.
My maternal grandmother lived until I was in junior high, I think.
My paternal grandmother died around Thanksgiving during my sophmore year in college.
My kids have only ever known my parents. Their paternal grandmother died before they were born and my husband doesn’t see his father. I’m not even sure if he’s still alive.
I do miss my paternal grandmother. She was very sweet and kind and spent a lot of time with us. My other grandmother was more distant and had some issues I didn’t know about until after she died. (Basically, she resented the fact that my mother moved away to the “big city” after she married.)
Both of my maternal grandparents died when I was 19. My paternal grandfather died when i was 30, and my grandmother when I was 32.
My 10 yo son, through assorted divorces in my and my parents’ generation of our family has 10 people he legitimately calls grandparents, all alive and well. He met my paternal grandparents before they died, and has one great-grandmother on his dad’s side still living.
Both grandfathers were gone before I was born.
Paternal grandmother died when I was just an infant (and according to my three older brothers, I got gypped – she was apparently the spoilingest spoiler that ever spoiled).
Maternal grandmother died when I was about six or seven. I don’t recall too much happiness with her…she had a stroke when I was four, and was left in rough shape. I remember spending a lot of hours teaching her how to read, but not much other than that.
That’s what happens when you come along late in life, I suppose.
I just wanted to add:
My paternal great-grandfather diesd when I was 4
And my two materal great-grandmothers when I was 5 and 7.
I’m 53, and I still have a grandparent, my maternal grandmother. She’s 103, writes poetry, has half of her own teeth, and has voted in 20 straight presidential elections. It would be one more if she could have voted at the age of 18, as one can now. God willing, she will vote in November.
I like having good genes!
My last grandparent passed away when I was less than 2 years old. I have the faintest impression of him. My sister just had a daughter who has 4 great-grandparents and 3 grandparents.
Both my paternal grandparents died before I was born. My maternal grandfather died when I was 23, my maternal grandmother when I was 35 (I’m 37 now).
Hopefully many, many years older than I am right now.
(I’m 22 with 2 living (and fairly healthy) grandparents.)
I started with four grandparents.
My maternal grandfather died when I was 5 (heart attack).
My paternal grandmother died when I was 10 (complications after a decades-long fight with leukaemia).
My paternal grandfather also died when I was 10 (he killed himself on the morning of what would have been my grandmother’s birthday).
My maternal grandmother had Alzheimer’s and stopped recognising me by the time I was about 15, but she died when I was 21.
My daughter will turn one in April and she has four grandparents and one great-grandmother (my husband’s paternal grandmother).
I am 28 and I still have both maternal grandparents (plus the woman my grandpa married and divorced after he divorced my biological grandma…she is a close family friend and I call her Grandma) and my paternal grandpa. My paternal grandma died on Sept. 8, 2001, when I was 21. That was a fabulous week, as you can imagine. Blah.
On my dad’s side, I never had any great-grandparents that I knew (my paternal grandma’s mom may still be alive, but I think she’s dead. I never met her because she was estranged from my grandma, and because she had some sort of dementia and probably would thought I was a talking ficus anyway). On my mom’s side, however, I grew up knowing my maternal grandma’s parents through letters and stuff, because they lived in Florida and didn’t visit a lot, and when I was in my late teens, my great-grandma died and my great-grandpa had to move into my grandma’s house, so we took in their cats. He didn’t die until 2004 or so, when I was 24.
I also had only one left when I was born (my paternal grandfather) who died just before I turned 3.
My dad had an unmarried older sister who essentially was a surrogate grandmother, so I didn’t entirely miss out on the experience.
Paternal grandfather died when I was 11.
Paternal grandmother, when I was 18.
Maternal grandmother, when I was 41.
Maternal grandfather, when I was 42.
As you might have guessed, my father was the youngest of his sibs, and my mom, the olders of hers.
Paternal grandmother died in 1926, 33 years before I was born.
Paternal grandfather died in 1943, 16 years before I was born.
Maternal grandmother died in 1946, 13 years before I was born.
Maternal grandfather died in 1968 when I was 9.
I have always had a wealth of grandparents; I’m very lucky in this regard. I had to jot down a mini-family tree to get it straight in my head. I started with three grandparents: both of my mother’s parents and my dad’s mother. My dad’s sperm donor is alive, but was abusive and is exiled from the family. I also had three great-grandparents: my dad’s maternal grandparents and my mom’s paternal grandmother. When my mom married when I was 6, I inherited an extra set of both grandparents and great-grandparents.
To date, all of the grandparents are alive as is one great-grandmother (at 95).
Paternal grandfather died about 15 years before I was born.
Paternal grandmother died about 7 years before I was born.
Maternal grandfather and grandmother died within 3 months of each other when I was 20.
I was kind of a late baby for my folks (eighth of nine kids) so both they and my grandparents were older compared to most of the people I knew in my generation.
I was 36 when my 94 year old grandmother died 5 years ago. It was one of saddest periods of my life. My other grandmother died when I was 16 and my two grandfathers died when I was 2.
I started with 3 grandparents and 1 great-grandfather. I lost them at
5 yrs (great-grandfather)
8 yrs (maternal grandfather)
20 yrs (paternal grandfather)
31 yrs (maternal grandmother)
I remember them all very well, as they were definitely in my life while they were alive.
My niece has a picture including her, her great-great grandmother, great-grandmother, grandmother and mother (my sister). She is now 17 and her great-grandmother is still alive. I wish I could get some of my brother-in-laws genes. 
Jammer
Let’s see:
My paternal grandfather died in Pearl Harbor when my father was 1 so I never knew him.
My maternal great-grandmother (grandfather’s mother) died in 93? when she was 99 and I was 20.
My paternal grandmother died in 1998 at age 99; I was 31.
My maternal grandfather died in 2002 at age 77 (super healthy but he picked up a liver bug when stationed in SE Asia as a marine); I was 35.
My maternal grandmother is now 82 and still going strong and living independently. I figure she’ll make it over a 100.
Last rites.
To answer the OP’s question:
My paternal grandfather died in 1964, when I was four years old. He had a heart condition which was then fatal, but is now routinely treatable. In contrast, my paternal grandmother survived at least seven heart attacks, including one or two massive ones, and hung on until 1996. She was 87 when she finally succumbed.
My maternal grandmother died at the age of 84 in 1995, while her husband made it to January 5, 2001 (he had Alzheimer’s, as had his wife, but accomplished his stated goal of seeing in the TRUE turn of the millennium). He was 91, while I had turned 41 about four months earlier.
