for what its worth at this time--I am the ggson of Jeremiah Tierney born in Ireland m Sarah Jane Arnold born in Scotland. Their son, Michael Tierney b Ireland age 26, my grandfather, was married to Anna Austin in Pittsfield Illinois in 1890 and listed both of his parents on his application for marriage. This is as far as I'V been able to trace. I do have a copy of the marriage license to which it is attached. I'V been looking for over 30 years for more info. to no avail. If it helps let me know.
