Interesting info on Jane Gilpin Dever. I found her marriage to George Dever in PA in 1890. He was born in Ireland per the marriage cert. She is listed as Jennie but I've tied that name back to her on other documents so I'm confident it is her.
She has her baby in Ireland in January, 1892. I found her and the baby returning to PA in August, 1892.
I'm 1900, George is remarried to Teresa and the census indicates they've been married 5 years by 1900.
