Lewis had another child out of wedlock, who calls herself Suzan Lewis (née Minoret), whom he never acknowledged despite her parentage being confirmed by DNA tests. She isn’t mentioned among those disinherited, presumably because to do so would require Lewis to admit he was her father in the first place. (Though even this conclusion is pure conjecture without Lewis around to confirm—see how quickly things can get murky?) However, since he didn’t name her at all and he was so intentionally specific in naming those whom he did intend to disinherit, it could be argued that she retains some claims to his estate.
