Yours is an intriguing question which begs the question why? None of my business perhaps, but I would imagine an absolutely impossible one to answer.
Lloyd, as the first letter Ll (Welsh alphabet) indicates is a Welsh name. Until quite late in their history the Welsh used the patronymic system of naming so Lloyd would have been linked to the name of his father, and then his sons would link to Lloyds. So if his fther was Madoc for example, he may have been Lloyd ab Madoc, then his son Ieuan would be Ieuan ap Lloyd etc.
In conforming to the English tradition that had adopted a family surname some of these Welsh patronymic names transformed into new surnames with the ap or ab, for instance Ap Rhys became Price, Prys or similar; and some merely adopted one of the family forenames as a family surname, such as Lloyd.
The consequence of this is that there will be many, dozens or even hundreds, of separate families with the name Lloyd which are not in any way linked to each other. Who is to say who the first Lloyd was in any one of these families, let alone which family adopted the surname first!
