Hi Gwen,
Went to library today and found the death notice for
Edmond Wilson Lascelles as follows - Cork Examiner Apr 11 1855
"March 29th, in London, Captain Edmond Wilson Lascelles, late of
H.M.'s 22nd Regiment, aged 54."
Cork Examiner Aug 24 1865 for John Francis Lascelle
" On the 20th inst. at Springfield Lawn, The Park, Cheltenham,
Captain John Francis Lascelles, R.N. of Thrisk, Yorkshire"
Cork Examiner 1.05.1865 for Hon. Edwin Lascelles
"On 25th ult, at Wighill Park, Yorkshire, the Hon Edwin Lascelles, suddenly of apoplexy, aged 64"
I didn't get a chance to see Lady Caroline's one as my time was up. It would seem that the Hon Edwin was possibly Caroline's husband. You will probably find them on the peerage site.
For copyright reasons I can't post the actual newspaper articles here. If you want them I can scan them to you if you send me a PM with your email address. Under copyright law they are for personal use only.
Hope you have found a little clue in the above to help your search.
