I note with interest the posts on this thread. My GGGrandfather, Steven (or Stephen) O'Shaughnessey was reportedly from Limerick, and as far as I can piece together, immegrated to US in about 1850 and settled in the Chicago area. He married a Nancy O'Conner and one of his daughters was Elizabeth. She married a John W. Geiger in 1882 or so. He had a sister, I believe her name was Mary. who married (John) McNamara in Ireland, then eventually came to Chicago area also. They had a son who was Bishop McNamara. If an;yone has any information on this family, feel free to contact me at firstname.lastname@example.org
. Thank you.
