Which one was he?

Last night, Larry mentioned that we still have a mystery concerning Grandma's brother, Charlie Sand.  He's the most elusive for a number of reasons:

What we know about him for sure is that he was closest in age to Elizabeth (Grandma), and they were children of Mike Sand and Louisa Rausch. ( In the photo, Elizabeth is second from left, and Charlie is on the right). He was born in December, 1887 and she was born in December 1889, according to the 1900 census, below.
(I always thought grandma was born in 1888!).

We know too that Charlie left home as soon as he could.  We found him next in the 1911 Canadian census in  Moose Jaw, Saskatchewan, but now he had a wife named Elizabeth.  He was 24 and she was 19.  Who was she, and how did they meet?  Well, the World's Best Researcher found her death certificate in Wenatchee, Washington where we know they eventually settled and owned an orchard...

WOW!  So Larry checked Minnesota census records for Frank Colwell , and found him, his wife Addie and oldest daughter Elizabeth in Popple township, Itasca county, Mn in 1905, when Elizabeth was 13.
So, when Charlie left home, it looks like he went to the logging camps up north. Evidently, Charlie and Elizabeth decided against Saskatchewan, cuz here they are in Mn:
In 1918 when men signed up for the WWI draft, we had a problem--there were at least six 'Charles Sand' registrations in the US, and more than one was  born December 18th.  Wow. So, which one was ours?  If this one is Grandma's brother, why did he say he was born in 1885?  Ahh, because that would make him OLDER, and perhaps less eligible for fighting a war.  (Cook is in St Louis County, near Duluth, Mn).

We know Charlie and Elizabeth were working for a mining company in Idaho in 1920--he was a foreman and she was a cook in their boarding house.  Here's a description of the company they worked for, we think.  The "town" in the 1920 census is Continental Divide, Idaho.

Oh, and look what else Larry found:
