I think I'd stay put
It's much harder to imagine having an effect on your own era than to go back to something where the history's already been written. I can't look at the past without getting nostalgic and imagining it better (or more interesting, if things were genuinly bad at that time) than it probably was.
Although, I'd love to meet my great-grandmothers Bessie and Regina. Maybe Pauline, too, I don't know much about her.
