Hello Kim, this is a difficult one, I would say his LNAB is Fhilippus or Philippus, after Fhilippus (Philippus) Ernst Wals the husband of his mother Jantje Heines (perhaps his father) but the problem is that in no deed a father is mentioned, while he is mentioned in his marriage certificate and death certificate with the surname Wals, I think it is best to keep as LNAB Wals because he is mentioned with this name in his marriage and death certificate
