Whenever heretofore real property has been conveyed to any person as “Trustee,” without naming the cestuis que trustent, and without declaring the purpose of the trust, and such trustee has thereafter, in good faith, made a conveyance of such property to a third person, in his own name as “Trustee,” without disclosing the cestuis que trustent, or without showing his right to make such conveyance, when the deed given by such trustee is otherwise in proper form and capable of conveying the estate intended--such deed and conveyance are hereby made good and valid and effectual to transfer, pass, and convey the estate, right, title, and interest of the cestuis que trustent for whom the trustee held, in and to such real property.
