Margaret Hamilton
Mrs Margaret Dallas

Married to James Dallas of Cantray (d. 1746), with whom she had at least two children, Isabella (1741-1792) and William (d. 1773-1774).

Margaret Hamilton was likely a distant relation of James Boswell's, probably sharing a common ancestor in Sir James Hamilton, 1st of Dalzell.

On August 23, 1773, in Aberdeen, Boswell went to see her, together with Mrs Isabella Riddoch (née Dallas, her daughter) and Prof. Thomas Gordon. Boswell did not write anything about their meeting, remarking only that he had not seen her since he was a mere child.

    Unless otherwise noted, the source for a dated quotation of Boswell's is generally the corresponding volume of the Yale Trade Editions of Boswell's journals.
