[Ger-Poland-Volhynia] Breakfast meal

[margaret]

If this is not a proper subject for this list I understand, but we were
discussing breakfast and very curious.
My husband's parents were both born in Pommern, came to US at young age.  My
father-in-law was born in 1878 and never touched milk that we saw, he put
black coffee on his cereal.  We were wondering what was the usual breakfast
for the people at that time and place?
