I am looking for Juho Heikki Hammar. He traveled to the USA in 1913

[Irmeli]

Juho Heikki Hammar born in Piippola,Finland 17.10.1883. He traveled to USA in 10 May 1913. This is all the information I have about him.
His brother Reeti born 5.12.1879 was in USA too but he came back to Finland. Brother Väinö Vilhelm born 3.7.1890 Piippola ,may have traveled to USA too.

Juho H. Hammar, born Piippola, last residence Rantsila, brother Fredrik Hammar, Piippola; arrived in Quebec, Canada on 10.5.1913. He traveled with Hilma Ervasti (?), age 11, born Piippola, who identified Fredrik Hammar as her uncle. So she must have been Juho's niece also. They were going to join Henry Kovala, Marengo, Wisconsin. Henry was Hilma's stepfather. Juho's passage was paid by his cousin and Hilma's passage was paid by her step-father. So Henry Kovala may have been Juho's cousin.

I found Henry Kovala, age 37, born Finland; wife Lena, age 63, born Finland; daughter Hilma H., age 17, born Finland, at Marengo, Wisconsin, in the 1920 US Census. But I can't find Juho Hammar.
