Online at the Maryland State Archives web site is an abstract of an item in the Chancery Court Papers which reads:
Date: 1821/04/21 12297: Nathan Waters vs. Mareen Duvall, John Carroll, Mary Carroll, William J. Duvall, Benjamin Duvall, Walter Duvall, Sarah Duvall, Richard Yarrington, Areanna Yarrington, Mr. Coulter, and Eleanor Coulter. PG. [Prince George County] Contract to purchase Goes Purchase. Accession No.: 17,898-12297; MSA S512-15-12104; Location: 1/39/4/
I suspect that Richard YARRINGTON and Areanna YARRINGTON are the Richard YARRINGTON & Arry/Anna DUVALL who married 8 Feb 1798 in Anne Arundel Co., MD.
There are two sources for this marriage record, one who says she was Arry DUVALL and one who says she was Anna DUVALL.Until I see the original record, myself, I can only guess she was Arry Anna = Areanna = Arianna.
