Just to fill in data on the "sisters" mentioned.
Esther Sutherland,baptised March 1811,Rathkeale,Co. Limerick (Father-John,Mother-Catherine)
Married Alexander Broadfoot,St. Marylebone Westminster June 1828
and probably
Elizabeth Sutherland,baptised June 1794,St Marylebone,Westminster,(Father-John,Mother-Susanna)
Married William Stavers,Saint James,Westminster,June 1810
and possibly,
Susa Sutherland,died 1803,Westminster.
(and as I have said before John Sutherland then marries Catherine Daly in 1809)
I will concentrate on trying to see if there is reference to John Sutherland's will(an Index of Wills suggests there was one dated 1847),in he hope there is further mention of Jess(i)e.
