Kevin, I also have my geneology done for the Tjeerdsma line back to about 1675 from Oudega, Friesland, Holland. Also, my Greatgrandfather met and married his wife in Harrison, South Dakota. From my understanding, there were two main Tjeerdsma family lines in Holland. It appears that both lines migrated to the United States. My Greatgrandfather came to the US in 1893, made his way through Peola, Iowa, then to Harrison, S. Dakota, and then from there to Burlington, Washington. Today I live in Utah and have spent some time in Holland doing research on the Tjeerdsma line. Contact me at
btjeerdsma@aol.com if you desire to know more. My research is quite complete and documented.
