My great, great great..Grandmother was Catherine Oliver born maybe in late 1700's - early 1800's in Ireland she was married to Michael Leahy same time line, they had 2 children that I know of Catherine Leahy and John Leahy born early 1800's in Ireland,
Catherine Leahy married Patrick Griffin (in Australia) who was the son of Martin Griffin and Hanora Walsh, John Leahy married Catherine Griffin (the sister of Patrick) the other Griffin brothers went to America and settled there.
The GRIFFIN, LEAHY, WALSH AND OLIVER FAMILIES WERE VERY GOOD FRIENDS.
