According to The Founders of Anne Arundel & Howard Co.'s MD, etc. by J. D. Warfield, Sarah married 1st Jacob Davies, the Mayor of Baltimore, and was Sarah Davies, widow, when she married Theordorick Bland in 1801. But Jacob Davies, the Mayor of Baltimore was born 29 May 1796 (so was 5 years old in 1801), was the mayor from 1846 to 1850, and he was very much alive when he married Mary Betts in Baltimore on 18 Sep 1821. Did she marry the mayor's father and was therefore his mother and not his wife???
