In Oklahoma, what year was the fire that destroyed all the records (marriage, divorce, ect.)?

Answer 1

Since these are kept by county in most states, I don't know that there could have been a fire that destroyed all the records statewide.

I do know that in 1865, all of the records of everything in most Southern States were destroyed by fire. Those that weren't were voided by government decree anyway.

Answer 2

I couldn't find anything that listed Oklahoma's public records (marriage, divorce, etc.) being destroyed by fire.
However , I did find that in 1890, all census records were lost

~~1890 Federal Oklahoma Census Records were completely destroyed by fire, however, the 1890 Veterans and Widows census schedules for Oklahoma did survive the fire and can prove helpful as a census substitute.

My great grandparents were from what was known as the Arkansas territory, which at that time included Okalahoma... Both of my grandparents and their 7 children (including my mother) were from Oklahoma as well, and I've never had any problems reseaching records in that state, other than the 1890 census.
So not ALL records were destroyed... but possibly some local records throughout the state were destroyed at one time or another.

Answer 3

How's this for service, Peggy?

the 1890 Veterans and Widows census schedules for Oklahoma did survive.
