Hi, MisterSynergy. First let me wish you a happy New Year!
Then, do you thing that the deleted item could you restored? I could add more authorities like ORCID* and theses.fr IDs, and link it to Jean Lemaitre (Q33820736) with doctoral student (P185). Also, I would purge the item from all "personal" datas (as like as Twitter account), so it could be no matter for anyone.
*Btw, I believe that a bot is massively creating items for corresponding ORCID IDs not matched in Wikidata (I saw it several times lately). So I suppose that the item will be recreated one day or another.
