Looking for unknown relative(s)

So for the past 6 years i have been hearing stories from many people in and even out of my close family circle that my great grandmother jumped off the bridge in eel river, and passed years ago when she did this. She was born as a labillois.. for years i have been trying to figure out my family tree since i have little to no contact with this side of the family due to certain reasons i would rather not mention. I have tried looking up articles about her death for names, i have tried asking around to people who might know and i am at a loss. I really would love to learn more about this side of the family i was disconnected with at a very young age. If anyone knows anything about this situation or who she was or if it was just something that was told to me and is false information please let me know if you can. Thank you in advance.
