I'm sorry, but I have very little info on my Manke family ancestors. The family story says that the Manke ancestors were friends with a Russian Czarina. I have tried to trace the family, but I'm having a hard time due to the fact that I find that they have changed their names .. for example I have Gertrude, aka Getrude, aka Kate, etc.
Perhaps they were not only friends with the Romanov family, but were somehow related, and feared for their lives, and therefor kept changing their names. In any case, I'm finding them hard to track. I guess it is possible that they could have originally lived in Minnesota or Wisconsin befor moving to Chicago, but I have yet to find any proof. (other then census records, again, with different first names).
I don't know anything about a relation named Snow. Perhaps you are referring to my mention of Snow which is a street name listed in the Chicago directory:
Chicago Directory, 1894
Manke, Julius, laborer, home: Elston Ave. near Snow
If I should come across any new info I will post it in the message boards.
Thanks so much for your reply.
