Thankyou Frank. You wrote : "Picture of the Court House in Batimore (I believe) 1784. The article speakes of the 1768 act which was passed "for erecting a court-house and prison for Baltimore Co and in the Town of Baltimore and for making the sale of the old Court House and prison." Robert Adair with Messrs. JB Borley, John Ridgely, John Moale, Robert Alexander, William Smith and Andrew Buchanan who were appointed commissioner to build the Prison and Court House which the act directed should be constructed on the upper part of Calvert Street, next to Jones Falls."
I believe Robert Alexander may have been Robert Adair's brother-in-law, and that William Smith (relative of Paca) may also have been connected. Wonder if the descendants of Robert Alexander may have more information on this Robert Adair, brother of Elizabeth who m. John Posey, neighbour of George Washington ?
