Someone mentioned Jessie dying of TB aged 34 in 1904. I don't have the original certificate but I do have a note from the index on scotlandspeople and that states 38.
Given that year of death and age at death along with a place of birth of Dalmellington I believe your Sloss side goes as follows:
Jessie born 27/03/1865 to Robert Sloss and Margaret Lees
her siblings: Andrew, John Lees, Mary, Robert, James, William
Robert married Margaret on 04/03/1864 at Ayr, New Cumnock
Robert born 8/3/1843 to James Sloss and Jessie Ferguson at Dalmellington
his siblings: Agnes, Elizabeth, Janet, Mary, Jessie, Barbara Rae (this last one I'm unsure of)
James married Jessie on 21/08/1838 at Dalmellington
James born 21/8/1817 to Robert Sloss and Mary Rae at Dalmellington
his siblings: Duncan, Elizabeth, Mary, Quintin, Thomas, Robert, John
Robert married Mary on 14/01/1816 at Dalmellington
Robert born in 1793 to James Sloss and Elizabeth Armour place unknown but probably Ayr, Dailly
his siblings: James (1791), James (1794), Jean/Jane (1803)
Hope that helps a bit.
