What Sources do we have to prove that Isabeau Verdette and Antoine Mallan had other children besides the ten month old daughter (NN Mallan) listed to travel on the China in 1687?
As none of these above three arrive in the Cape on the China, it has been presumed that they all 3, died at sea, or that they never boarded.
If, however, the couple have the 3 more sons listed on Geni: Barthélemi Mallan
Henri Mallan & Jean Mallan
then that may be proof that they survived - either staying behind in Rotterdam, or arriving on another ship after the Batavia fund of 1690 recorded Huguenot recipients.
We need the sources for these three sons, though. Private?
