Origin of free liver

First recorded in 1705–15

A free-liver, he could not realize that hungry people should ever think of better food.

His Excellency the Minister |Jules Claretie
To a free-liver, as she believes me to be, who has her in his power!

Clarissa, Volume 3 (of 9) |Samuel Richardson
I only am in danger: but were I the free-liver I am reported to be, all this could I get over with a wet finger, as the saying is.

Clarissa, Volume 3 (of 9) |Samuel Richardson
He, already a free-thinker, was now revealed as a free-liver.

Saint's Progress |John Galsworthy

His rich voluptuous strain has more of the poet than the free-liver, and his general tone is curiously modern.
