[NB: after the death of their mother, the children Hijmans came under custody of Jonas Samuel Levi (Goudsmit) and Jacob Samuel Levi (Groenewoudt) -- Hijman’s son Benjamin is stated as a cousin of Jonas, which could mean Hijman is a brother of Jonas; but so far there is no other proof and he was not named with the patronymic “Samuel (Levi)”, as the other brothers and sister usually were]
