Nice catch. My eyes lit up when i saw, two lines above her, "Minnie King" as that was her m-i-l's name. However the age for Minnie is given as 30, and not 45, that's not a mistake anyone is liable to make. But i can see someone equating NB ("way up north") with Maine.
Yes, I also thought that catholic might be her religion based on her father's name. And i have seen her referenced as Jennie, Jeneva, Geneva, Eva, and i should probably look for your suggestions too. But i was unaware of PANB until reading Christine's reply above a few mins ago. I will poke around there.
The spelling of her mother's name i got from Jeneva's marriage record, so it's quite possible that the person writing it down mispelled it.
I do think that at her age Geneva eventually remarried. That would make my task even worse! But since i grew up in the same town where she and Ernie were living in the '15 census and when he died, and was related to a big chunk of the populace one way or another, and it being a small town, I think she would have been known. One of my aunts ( b.'26) that's still alive has no recollection of meeting Eva nor any knowledge of what happened to Jennie, (And yes, she's still quite coherent :)
So, this is fine work you've shown me and thanks for that! It shows me that i need to do some more research and thinking and research.
