A Brief Genealogical History of Wood County
Up to the year of 1848, Wood County was included in Nacogdoches County, when Van Zandt County was segregated from Nacogdoches. Van Zandt County then included the present counties of Van Zandt, Wood and Rains.
Wood County was organized in 1850, but not in time to be counted separately in the federal census of that year. Wood County residents are included in the Van Zandt County federal census for 1850. Quitman was designated as the county seat and remains so today.
Rains County was taken off the northwestern portion of Wood County in June of 1870. The portion of Wood County cut off into Rains runs about a mile east of the Flat Community to the east edge of Point.
In 1878, the Wood County Court House burned, with the loss of all county records. Genealogy researchers must seek alternate sources of information for the period from 1850 to 1878. Many land deeds were re-filed after the fire, and these records of re-filed deeds have been printed in the quarterly newsletter of the Wood County Genealogical Society.
I have the same problem you do as to lost marriage records in Wood county due to the 1878 fire and land records.
