I probably do exist it a bunch of other timelines, but since I was born in the mid-1980s, I'm probably only limited to TLs with recent PODs. Furthermore, considering where my family came from (Britain and the Ukraine), almost any pre-1950s PODs are guaranteed to wipe me out of existence. My dad's family emigrated/fled from the Ukraine in the 1940s, and they were not well-off to begin with. Without WW2, there's a good chance they'd still be there today, and I would not be.
Ironically, it seems that Josef Stalin is partly responsible for my existence. I'm sure he'd be pleased to know that. Or not care. Either one of the two.
