Thank you for your response!
I am also wondering about Herbert and Anna now.
I have the number for the closest library to Kooskia, given to me in an email. I will probably be calling them to see if I can find any obits for Rudolph, Louise Anna (Anna Louise), Herbert and Anna via the library.
What I do know is that my gg grandpa George Smith and grandma Emma lived in Big Timber, MT and later on his daughter and her children lived in Sun Valley, ID. I am not sure if that is a coincidence or not, I will have to ask my living relatives on that one.
Update: I just looked at the 1920 Idaho Census that was taken in Kooskia for Bert Smith. I think it's the right one as it lists him being born in NJ (he was) and his parents being born in NY (they were) and it seems he got married in MN to Ethel Allen and there oldest daughter was born in MN and also in their household lives their niece Doris Laird. It lists Doris's father has being from the US and her mother being born in NJ.
