Genealogy in Utrecht
There were no particular naming traditions in Utrecht that researchers have to take into account. People used regular last names long before the introduction of the civil registration.
Many records of the province of Utrecht are kept by the Utrechts Archief. Most of the marriage records of the civil registration from Utrecht can be found in Genlias.
Emigration from Utrecht
People in Utrecht were relatively well-to-do so the province wasn't particularly struck by any of the big emigration waves. There were quite a few entrepreneurs in the province, so there have been people who emigrated to newly founded colonies or tradeposts all over the world. In the middle of the 19th century, Utrecht members of the seceder church settled in Pella, Iowa.
