Thank you so much for your time and intrest Alicia!
I found out that my grandaunt Wendla Pyhtilä died 4.3.1949 and his first huspand Matti Johannes Pyhtilä 2.6.1933. They had at least 3 children. Thelma 24.12.1909; Ardell H. 1.7.1914 and Alvin I. 6.8.1918. Alvin died in second world war. Ardell married Saida Hill 14.4.1943. Oscar Hills daughter. Ardell died 9.1.1985. My only hope to find relatives there seems to be that Saida and Ardell häd children.
Finding these pieces of information has not been easy but interesting. Names has been changing cause of bad handwriting. At least I think so. Thelmas name has been interpreted as Laina, Delva, Thelma and in Finland Tellervo. I'm guite sure that they had only one daughter - Seen a fotograf they send to my grandmother, Surname Pyhtilä has also been written Pyhtilä, Pyhlilo, Pkytila, Phytila.
I´m wondering now how to get information on Ardell's life. I haven't found much from familysearch -files. Only the marriage -data. Is there some other possibilities to get more?
