Yes. I have zero relationship with either grandfather, though. My maternal grandparents did not like my mother's choices, including marrying my father, so they were completely estranged until my great grandmother died in 2009, and then they were mostly estranged, but then my grandmother died three years later, so my mom now has a relationship with her dad again (my grandmother was mostly the cause) and he has a relationship with my brother since he is the only grandson. I have zero relationship with him, other than seeing him at family get-togethers at my aunt's.
My paternal grandfather has no relationship with any of his grandchildren. We barely have conversations at family get-togethers; he usually talks to his sons and I talk to my dad's half brother (who I do have a relationship with) and his wife. My grandfather has not seen his other grandchildren in over a decade and has not met his great granddaughters. I think it's partially my step grandmother. Apparently, she didn't like it that my dad, who was my age when they got married, lived there so he could go to school (his mom lived up in PA, and her husband at the time was way worse). After he graduated law school, my grandfather made him move out, but paid rent until my dad could find a job. Also, my grandfather has the beginning stages of dementia, and although he may have forgotten that I graduated, she certainly didn't.
Catch 22, though. My parents met because my grandfather and step grandmother had a son, and my mom was their babysitter. So on one hand, I owe her my existence. On the other hand, she tried to make my father's life miserable, caused friction when my parents were dating, and has since kept her grandchildren away, though keeping the grandchildren away was partly my grandfather. So...screwed up situation. I've also been warned not to trust her.
Also, the last time I spoke to her was a few weeks ago when I mistakenly got a call from her aunt, who was absolutely hysterical, that her uncle had died, and her aunt asked me to call her because for whatever reason, she couldn't. Yup, so 100% awkward.
