I know your message was posted several years ago, so I hope you are still out there. I recently acquired a large box of geneology info that my aunt had worked on for YEARS. This Isabelle sounds like she could be one of my great-great-aunts. I'm pretty sure her husband's name was very similar to what you have. I will dig through my info and see exactly what I do have. Incidentally, I found this branch of my family in the 1880 census of Dixon County, Nebraska through www.familysearch.org---her father was Patrick Francis Feeney, married to Mary Feeney. Her older brother, Edward, was my great-grandfather. Take a look!
