c.o. stands for "in care of". Otto BLOCH is on Ancestry.com images 63 /
64. I found both c/o and c.o. meaning "in care of" for other passengers
on Ancestry.com images 55 / 56 .

On Paula's and Hans' lines, in the same column where Sigmund's name
and address appear on Otto's line, is the abbreviation c.o. and
a ditto mark. . Can anyone tell me what "c.o."
stands for?
