Hi Cousin!
I'm so glad to hear from you! Hjalmer was my husband Jerry's uncle. Please reply to my e-mail with details. I am working on a family tree about the whole family and have data on Hjalmer's children but only a few of his grandchildren and no details about your grandmother.
A distant relative in Sweden has a site on Ancestry.com. Do a search for "Christian Sjostrom".
