On 16/2/1869 he married Margaret Hislop in North Leith.
4 children found on the IGI:-
George Hislop Scott Kay born 23/9/1870 Leith
Mary Matilda Lennard Scott Kay born 21/10/1972 Leith
James Drummond Kay born 19/5/1874 Leith
Charlotte Scott Kay b 19/5/1874 Leith.
I have searched my 1881 census discs for this family and can't find them
Any ideas anyone?
