I was just about to type I wonder if there are naturalization papers when I read your post,Monica! There are a couple of shipping records for him from Hong Kong and an entry in the 1920 and 1930 US census( crossed out in the 1930 census). His year of immigration is different in each one - this often seems to happen in the US census.

Added: Having just read your last post, Brian, I think the point that both Monica and I are trying to make is that John Ross who died 1913 and Jane Ross , mother of John McDonald Ross, were not brother and sister. There is no documentary evidence to support that idea.
I agree that there wouldn't be a record of it....and yet John's mother was said by him to be Jane Ross and with and unknown father. It's possible. In the tree with Alexander and Isobel as parents ( grandparents to John), as he is listed at Grandson. Alexander is 58 and has a 20 year old daughter so could have an older son too.
Where is his mother and father of the grandson John? Like I said...coincidence that our John M Ross would be the right age, and just by fluke named all his children after other family members in this group, even the last one Fraser!
I agree with the premeditation of the shooting! Pretty hard to deny that something was in the wind if you did a will a day or so before!
