I found George Hodgson in Scammon on the 1910 census, which puts his birth around 1860.
If Alice's age is right on the 1911 Scotland census and the travel documents, her birth is around 1872.
I don't have an Ancestry description but there was a Kansas state census in 1915.Looking at the 1920 census Grace may have been adopted by William and Eva Imhof(f) who also have an adopted son Roy Sturn.
