Hi,
Also any information of Roderick Murray - Donald's brother to Canada, I think Canada was around 1938.
I can't find a Roderick Murray going to Canada in 1938 and I also note that there is no Roderick with Catherine and Daniel/Donald in the census record I found.
But I did find this.
1901 Scottish census
Stornoway Ed 1 page 3 line 13
Address
9 Newton StreetRoderick Murray 13 born Stornoway
Father Robert Murray 31 born Stornaway
Julia Stornoway 31 born Stornaway..
9 Newton Street is the same address that you gave for Donald and Catherine in your second post.
So correct address, wrong parents.
