I have the book, "District of Columbia Marriage Records 1870-1877" compiled by Dorothy S. Provine. This book is an index to the volumes entitled Record of Marriage that were created and maintained in the clerk's office of Supreme Court of the District of Columbia (now District of Columbia Superior Court). Entries show the names of the bride and groom, the date of marriage or granting of license, and the volume and page of the Record of Marriage that contains that entry. Entries in which the date is followed by an "L" indicate that the date shown is the date a license was granted. Entires without the L show the date of marriage. According to the book, these Records of Marriage have been transferred to the DC Archives. I found the following two entries for that period. I'm sending them along in case they are of interest to you. Marders, Charles F. Madigan, Mary 11 Sept 1872 L 4:233 Marders, W. H. Goldsmith, Margaret D. 10 Sept 1874 7:112 Barbara
