Countries: Russia/Prussia/Poland/Canada

I am looking for any information available for John Tony Tulak. I have managed to locate three separate records but I do not know if two of the three records belong to the same John Tony Tulak. There is a family "story" that goes something like this: John and a brother or two (possibly the father as well) were the only surviving male members of "The War" (possibly the Prussian War) and once the war was over they immigrated to Canada. That is all the information I have been able to glean from living family members since his wife has passed away.

Family information I have been able to gather is as follows: John Tony Tulak (birth date not yet verified of 15 Sep 1886 in Miedzy Brodzie, Lipnicke, Austria, Poland) married Dollie (no middle name) Zacharias, b: 3 Jun 1908 in Brandon, Manitoba, Canada, d: 22 Dec 1997 in Osoyoos, British Columbia, Canada. John and Dollie had at least seven children: John Douglas (Doug) Tulak, Joseph Julian Tony Tulak, Joan Lucile (Tulak) Fancy, Dolly Fay (Tulak) McPherson, Mary Elsie Charlotte (Tulak) Robins, Brian Tulak, and Jeannette Gail (Tulak) Chatterson now Sholander. Two of the daughters, Joan Lucile (Tulak) Fancy and Dolly Fay (Tulak) McPherson, are married to Americans and living in the United States.

Of the three records I have been able to locate, only the first record I know for sure belongs to the John Tony Tulak in my family tree; the other two I do not know for sure if they belong to the same John Tulak. Here is what I have so far:
