His death date, which Burkes volumes show as both 1831 and 1841 is down as 1841 on an old Trotter family tree of which I was given a copy in June 2003.

FreeBMD has a death record for a George Welbank whose death was registered in Q1 of 1839 in Nottingham district, vol 15, p. 376.  It would be interesting to see the death cert but not worth the present-day cost; perhaps I shall wait until the whole thing has been digitised by HMG.  There is no doubt but that he died before his sister inherited Horton Manor in 1868 and from the terms of the odd will, his death was long before that.

See the section on Wills for evidence that he died circa June 1842.

In 1832-4 Pigot’s Sussex has this entry:

“Welbank George, esq. 32 Cannon place”
_______________

Not found in the 1841 census.
_______________

See his Will Notes for the info about his death in Quebec, Lower Canada with a date of 3 Mar 1842.

I have tried every way I can but cannot find any record for his death in Quebec, neither on FindMyPast nor FamilySearch nor some web-sites based in Quebec province.

But Margaret of the Welbank family did find his burial and it states:

His will, dated (I think) 9th June 1834 was proved in the 30th Nov 1842 and is transcribed by me as:

“This is the last will and testament of George Welbank of Brighton in the County of Sussex gentleman I give to my friend Samuel Goodman whom I appoint executor of this my will one hundred pounds and I give devise and bequeath all my real estate of what kind soever amd all the residue of my personal estate unto my friend Emma Ekin(?) daughter of the late Mr Ekin of Huntingdon(?) to ?crow? to her the said Emma Ekin Ekin her heirs executors and administrators absolutely and for ever in Witness whereof I the said George Welbank have to this my last will and testament set my hand and affixed my seal this 9th June 1834 . George Welbank ... signed sealed published and declared by the said George Welbank the testator as and for his last will and testament in the present of us whio in his presence at his request and in the presence of each other have hereunto set our names as witnesses, Fredk Cooper solr Brighton -- Albert Geary  W J Williams his clerks.

The probate clause was, again transcribed by me:

Proved at London 30th Nove 1842 before the worshipful Robert Thomas(?) Doctor of Laws and Surrogate by the oath of Samuel Goodman the sole executor to whom admon was granted having been first sworn duly to administer.  the letters of admon of the goods of the said deceased granted in the month of July last to Mary Elizabeth Brown wife of William Brown the natural and lawful sister and one of the next of kin of the said deceased un the the suggestion the he died intestate having been first voluntarily brought in and ?revoked? by interlocutory decree as by acts of Court appear.
