Johnson (b. Gustafsson) Viktor Emanuel b1886 Eland, Finland. Emigr 1909. Children in US

[Mikaela Johansson]

I managed to trace my father's roots to a brother of my father's grandmother he was born as Viktor Emanuel Gustafsson.
My father's maternal grandmother was Edith Kristina Gustafsson she was born on the 24/7 1894 i Björby, Eland part of Finland.  
He was born in Finland, Eland in 1886 on the 3/11 and he emigrated to the States in 1909.
Viktor changed his surname from Gustafsson to Johnson after his arrival in America.
 
later he settled down in Mineral County West Virginia and married a Martha Marie Paugh, born in 1899 from Bloomingsdale, Maryland.  
They got married on the 6th November 1915 and so far I've found records of three children born out of this union.
 
Helen Viola Johnson, born in 1916  
Charlotta M Johnson, born 1918/1919
Vincent Emanuel Johnson, born 1920.  
 
It's a possibility that Charlotta didn't live very long since there's no further records on her, or she coud have married.
I have been unable to find any information on her.
I know that Vincent was married in 1942 but single again in 1943.
Now I'm interested to find out if Vincent , Helen and Charlotta married and had children of their own ?
 
Any information would appreciated and I'm aware of the fact that it's very possible that John Viktor's grandchildren may still be alive. Thus this could be the reason why I havn't been able to find any records on them...  
 
By writing this in English instead of Swedish I'm hoping that someone out there might be able to help...  
 
Sincerely Mikaela

Oj, tack så mycket Anders.
Förhoppningsvis så fick Vincent eller Helen egna barn.
Annars så har släkten Johnson Paugh dött ut...

Har nu studerat framförallt dokumentet med Pearl Virginias död.
Tydligen så avled Charlotte och Isabel av dysenteri samma år med endast en dags mellanrum.
Tyvärr kan jag inte urskilja vad dödsorsaken för Pearl Virginia ska vara.
Ser ut att vara skrivet på latin bacillus... någonting.
