I too am reaching Taltys from Carhuduff, Milltown Malbay, County Clare. My ancesters came to the US around 1847. The family included Michael Talty and Bridget Doherty. There children were: Anthony, Charles, Michael, Hugh (1828), John (1830), Mary, Margaret (1832), Johanna, Peter Paul (1845). They were from the Parish of Kilfarboy, Diocese of Killaloe. I have Peter's birth/baptismal certificate from St. Joseph Catholic Church.
From what I have been able to locate thus far, my Taltys first went to Quebec. They later moved on to New York (have not yet determined what part but think it may have been Buffalo). From New York, they moved on with most of them settling in Dubuque, Iowa; however, others lived for a time in Waterloo, Iowa; Memphis, TN; Manchester, NH; and Maysville, KY.
A good place to search for information is the LDS Family History Library. They have a website where you can search the IGI and you will find several Taltys living in the Milltown Malbay area of Clare County -- www.familysearch.org
