Simon,
Love it when people start asking about regiments--- it means you're being bitten by the bug bad.
:bravo:
Before I turn to the units. Let me put a plug in for reference books. Below is a picture of one page from Jim Turinetti's book which is still available.

This is not the only book available, but there is a lot of information crammed into a small place, broken down by Regiment. I think you can buy this for less than a shoulder strap. Other people have more favorite books, and every single book has mistakes in it. But they are the springboard to further research! :study: :study:
As you can see from the picture. JR 170 was originally from Baden.
the 400 series infantry regiments were later war developed and I believe these two were from Prussia.
JR 47 was from Prussia, but more specifically, the province of Posen having many German citizens who spoke Polish.
JR 27 -- Prussia.
JR 153 -- Saxe Altenburg.
Foot artillery regiments before the war went up to 20. I am not sure about number 30 without looking it up.
Great to meet chasing these things! :smilebox: :smilebox:
