Hello Larry,
I have looked at your Looney family DNA project and the one shown as L-5 that points back to the Isle of Man.
• John, b c1700 Isle of Man m Margaret Kelvie.
John, b c1748 Isle of Man m Isabel Camaish.
John, b c1788 Isle of Man m Rachel Redhead.
John Joseph, b 1819 Isle of Man m Rosanna Vinecombe.
George Henry, b 1861 New Zealand m Julia Sampson - L-5.
This Looney family is missing a Generation.
John Looney who married Isabel Camaish - was born, 14 Jan 1770 - the son of, Daniel Looney and Isabel Cashin.

To trace back further you need to search the, Land Records and the Wills and the Parish Registers, all available at the Manx Museum.
hope this helps,
