My son was asking about family history and I came across your post. I am the son of Paul Henry Daniel Halkola. Who is the brother of David T. Halkola. Sones of Aino Lilja Kantonen (Halkola). I read that you had contacted my uncle David prior to his death, I am sure he's was able to provide much more information than I can. If you are in need information I can help with please feel free to contact me.
