John & Catherine had a large family of 5 boys (Thomas, Joseph, Major, William & John) and 5 girls (MaryAnn, Margaret, Catherine, Sarah & Matilda). John died in 1887, leaving a will filed in Ireland. From the wills facts, he did not immigrate to America. Obviously you are correct that Major and Sarah are siblings. I don't know if you are still getting genealogical information at this site, but thought I should post this the information.
