Can’t help with Kennedy side. However here is something on Kemple side.
This is a bit of a longer story but here is short version. The Kemple family still lives in the Looscaun area in a town called Rossmore. Working up the family tree they cross my family tree O’Shaughnessy who lived in Cloonoon next to both Looscaun and Rossmore. There is an O’Shaughnessy splinter also in Australia in an area called Kingower near Bendigo where there are a lot of ties to the same surrounding area of Looscaun, Coos, Portumna and Woodford.
