Various Carrolls came up - Alice, John, Sarah etc. when I did a search for Robert Crilly in Ireland. Details of the first half dozen showed no connection, so mystified, I did the search again with the same result.
The Robert Crilly I was looking for was born in Ireland in 1821 (I tried it with and without the date).He came to Australia, and died 1904 in Vic. leaving many descendants. Some details on the Crillys from Ireland forum.His mother was Mary Leckie; no Carroll connections that I know of. Mary.
