Historically, Thea is
the Anglicized spelling of the name Theia, who was the goddess of sight and shining light, the mother of Helios, Selene, and Eos.
My mother's maiden
name was Dailey which is described as the «
Anglicized form
of Irish Ó Dálaigh meaning «descendant
of DÁLACH» There are several variants
of the
spelling of Dailey / Daly, and I know that there are many Americans with this same ancestry.
