Actually we already had a latin name for a googol.  The latin name for 63
followed by the illion suffix is the formal name for 10 to the 99th power.

Then 10 times that number would be a googol.  The googolplex is 1 followed
by a googol zeroes which is a number too large to assign a meaning to.

We generally do not bother with formal names for really large numbers.  It
is sufficient to use the exponential notation.  We write 1 followed by a
hundred zeroes as 10^100.  We could write 1 followed by a googol zeroes as
10^(10^100).

The formal nomenclature can be seen on the web page

Large Number

Large decimal numbers beginning with 10 to the 9th
are named according to two mutually conflicting nomenclatures: the American
system (in which the prefix, mil, bil, tri, etc stands for 3 + 3 times the
corresponding number of zeros ) and the British system (in which the
prefix stands for 6 times the number of zeros ).
However, it should be noted that in more recent years, the
"American" system is now widely used in England as well as in the United
States.
The following table gives the names assigned to
various powers of 10 (Woolf 1982).
