My great grandfather, Olaf Hammerstrom (or Hammarstrom) emigrated to the USA ABT 1885 with his wife Johanna (Magnusson (sp?) and three of their five children; John, Victor, Hannah, Clara and Freida. The settled in WORCESTER, MASSACHUSETTS. OLAF's death certificate (1900) indicates VARMLAND as place of birth, however this conflicts with the family belief that he was from Stockholm. Much of the family history was lost due to death and the desire to assimilate into the new US culture. I would like very much to know how your search is going as there seem to be so few Hammerstroms!
