Tenacious to the End!
On the 1891 census at the Bedford Hotel, King's Road Brighton -
RG12/814/111/12
Is a Clarance(sic) Osborne b1863 a Captain in the ? Lancers (another hand has entered 'army') - but his pob is given as Dublin Ireland.
He is listed as son to the head John K Huntley b1818 Middlesex London
The entry after Clarance is Florence E Osbourne grandaughter b1867 Middlesex London
Not sure if he is yours or not
That is a most confusing census household! But I am sure it is him
thank you

I didn't find it because on Ancestry he was transcribed as a Huntley; also I presume Son is Son-in-law, or more technically Grandson-in-law, but I haven't yet looked into the family of Florence Ethel ELLIOTT [they were honeymooners, they married 5 Apr! i.e. census day]
Possibly Clarence was born in Dublin; in 1901 and 1911 he says Marylebone/London and that is where he was baptised; but I cannot find a birth reg. He was born 24 Apr, bapt 2 Jun, no indication on the Baptism register that he was born elsewhere, abode is given as 22 Dorset Square.
I agree it says carabiniers -- but I had thought he was a Captain at that time rather than Lieutenant
