Just making sure of this.
I've just found this statement in the Collins Dictionary of Mathematics (E.J. Borowski and J.M. Borwein, 1989) in the entry for "Lucas Numbers".
"(Named after the English mathematician Henry Lucas (died 1663).)"
This is rubbish, isn't it? Every single other reference to Lucas numbers attributes them to Edouard Lucas (1842 - 1891) (or whatever his dates were).
My information has it that Henry Lucas was not even a mathematician, "just" a clergyman and politician who bequeathed the Lucasian Chair of Mathematics in his legacy.
A simple conflation?
