Mathias, Catherine, and @Maximilian (6 months old at the time - which would make his DOB approximately November of 1864 and his death approximately April 1865) Watembach boarded the Louise Kohn in April of 1865 to come to America. Family stories (I am a Watembach) indicate that Mathias and Catherine lost a child on that voyage. Since Maximilian was the only child with them, one could assume that Maximilian died while on board the Louise Kohn at sea.
