Searching for Kinnally Descandents in Killucan & Kinnegad

Looking for descendants of Thomas Kinnally of Killucan, b. ca 1775. Believed to be brother of my GGGGrandfather Patrick Kinnally of Kinnegad, b. ca 1780. Patrick and most of his children emigrated to New York  between 1846 & 1850 leaving behind daughter Elizabeth (Bessie) who had married Thomas Nee. Their daughter Margaret Nee married John Wiley & was in Kinnegad around 1915.

Thomas' daughter Eliza (Bessie) & husband Thomas Harris/Harrison & children Ann, Philip, Mary, Thomas & Eliza emigrated about 1854. I've traced both families to the present in New York and would like to link with family in Killucan & Kinnegad. A man who grew up in Killucan told me there were several families in neighboring households called Kinnally but in Church and school they were called McNally.
