Hi, Lyle,
 
There probably isn't a single, simple, overall typology you can rely
on, but take a look at some early New England work by Jim Deetz and Ed
Dethlefsen.  Also, someone already mentioned Harriet Forbes' book.  Take
a look at the website for the Association for Gravestone Studies.  You
can easily "Goggle" them.  You might even pose your question to folks at
that website.  Their annual journal, Markers, is a good source.  Most
likely, you'll need to look at sources on a regional or even local
basis, since gravestone types prior to industrial production (and rail
transportation) varied significantly depending on folk tradition and
local craftsmen.
 
Best wishes,

Has anyone got a tombstone typology with illustrations for the period 

1600 onward?
