The death reg certainly seems to fit with this baptism.

John Emslie Kydd
Baptism - 14 Jan 1887
at Lyme Regis
Father - Robert Emslie Kydd
Mother -Annie Elizabeth Kydd
However I can't pin down a birth reg on FreeBMD for him. Is this because he and his sisters were born in Australia according to the 1891 census?
Umm, the John Enola/Emile/Emslie Kydd on the 1891 census is age 12 so born 1879. His mother is Annie E Moore (married) but the enumerator seems to have given her her maiden surname) If the baptism I found is your John Emslie then the death age is a fair bit out.
Added:- John's sister as down as born Australia in 1891 but in 1901 London
Births Mar 1/4 1887

None of this answers your original question but I found it interesting.
