Marriage license books from the Circuit Court of Queen Anne's County, MD are available online through the Maryland State Archives. The licenses are in scanned books and cover most years from 1817-1906.
The following license is for John Meredith and Elizabeth Hall. The date on the record is Feb. 5, 1823 and the officiant was Rev. Reed. A fee of $4.00 was paid. According to the information on the Maryland State Archives site, the date recorded by the clerk was the date of the marriage.
The entry is number 191 on page 64 of the book. The entries on this page are for 1824, so it appears the clerk may have made a mistake in recording the date.
According to a comment I received on a post about Francis and Mary Councill, John Meredith and Elizabeth Hall were the parents of Francis' wife Mary Meredith. They would be my 3x great-grandparents.
The commenter also mentioned that Mary's grandfather was Richard Hall and Mary had a brother named John Thomas Meredith. Mary and her brother were raised by Richard Hall after John Meredith died in 1830 and Elizabeth died in 1833. Thanks to H. Meredith for the information!
