Pembina County Pioneer Surnames.
These surnames were gathered from my Pembina County census databases (1880
- 1920), 1893 landowner database and the cemetery inscription database.
Names which appear very close in spelling may, in fact, be the same surname
but differ due to difficulties in reading different census years.
