I think there may be a connection here with some of my ancestors. My g-g-grandfather was Patrick J. O'Hare, born Ireland, came to US (Lee County, Illinois) c. 1850, married Bridget Hanrahan in 1863. They had 10 children that I know of. One of whom was James, born January 1868, died 1921. He married Catherine Walters about 1889. She was born November of 1867. They had 10 children. I have found them on the 1900 Lee County, IL census, but I know that at one time they also lived in Sprague, Washington. James' older sister also moved to Washington State and was married to Philip Dome.
I would be happy to share information with you if you think there is a connection here.
