Paul – you must take this data with a HUGE grain of rock salt. This Phillip and Christina Schramm of unknown! But foreign birth location - are living in 1900 in SD. They immigrated in 1889. Their children are listed as born in Scotland, which is obviously NOT the case if the parents were in the US prior to any of those births. So the census taker didn’t get the accent and wrote down Scotland - possibly instead of South Dakota?
This apparent same couple, still with children Fred and Helena of the correct ages, are in Sasketchewan in 1916 census, listing their immigration to Canada as being 1909 – and they have a son named Henry born the correct year as your grandfather – however he is listed as being born in Russia as are Fred and Helena, and 2 younger brother. Remainder of Henry’s siblings b. in Saskatchewan.
Think it over, and good luck!
