I have viewed marriage records from the field offices of the Freedmen's Bureau (Arkansas) however, I did not know that "records" were also forwarded to Washington D.C.--possibly records that were not included in the field office records.

In addition to former slaves legalizing their unions, I also found a marriage record dated March 1885, (Columbia County, AR) of a distant relative (Mary Adkins-Biddle) that was a teenager when slavery ended and on the 1870 Claiborne Parish, LA census she was enumerated with her man (husband) Henry Biddle and their children, Joseph and Fanny. Some 20 years after the passage of the 13th amendment, she and her man legalized their marriage.
