I wonder whether anyone has any information about a second marriage for Elizabeth, née Dominick, widow since January 1775 of George St. George [formerly Usher], Baron Saint George of Hatley Saint George.
The Complete Peerage, which usually mentions known marriages of widows of Peers, does not mention any subsequent marriage.
"He m. 18 July 1752, Elizabeth, da. and h . of Christopher DOMINICK, of Dublin. He d. s.p.m.s.(c ) Jan. 1775 when the peerage became extinct. His widow d. in Dublin , 26 Feb. 1813 , in her 81st year."
However, Lady Louisa Conolly, writing to her sister the Dowager Duchess of Leinster, mentions a "Chevalier de la Tour" a couple times as being together with the Dowager Lady St. George already in October 1775.
"Lady St George and the Chevalier de la Tour received me most graciously, and said all sorts of proper and fine things. Lady St George, I think, is a pretty woman, and very pleasing in her manner, and the Chevalier an unaffected, agreeable foreigner."
footnote in the Leinster Correspondence: "Elizabeth, heiress of Christopher Dominick, Esq., and widow of Usher St George, Lord St George ; married, for the 2nd time, the Chevalier de la Tour." [But it does not say whether they were already married when these 1775 letters were written.]
In another letter:
"And so I shall quit that subject to tell you that the Chevalier de la Tour, My Lady and Miss made me a visit at Castletown the other morning... Mr Conolly is vastly taken with the Chevalier ; he seems agreeable."
These mentions were in connection with the forthcoming marriage of Lady St. George's daughter to the 2nd Duke of Leinster.
Does anyone know whether Lady St. George did remarry, and the identity of the Chevalier?
