The Campbell/Carbery[Johnston] link is not supported by the maiden surnames in both families, going back to both of their grandparents (Helen Meehan of Donegal,a relative of Carbery through marriage, carried out the research and shared it with me). Helen also discoverd that Carbery was born in 1864, not 1866 as most of the standard books say. Anyway, if cousins, quite distant ones.

"Dew-Love": MLL is set at dusk/night, when the dew falls. Dew can also a symbol of freshness, possibly in JC's complex mind also one for purity/innocence/romanticism/idealism? Just a thought.
