The proceedings under the bankruptcy act (between 1936 and 1953) were in the name of "LEITH, The Right Honorable Robert Disney, Baron Cobham"
His 1933 divorce was under the name ALEXANDER.
I could not find a will in England and Wales, and suspect that there would be no reason for one, given that he was insolvent, his trustee in bankruptcy had all his assets in England and Wales which were insufficient to cover his debts, and that therefore the only assets he could exclude from this was sufficient to cover reasonable funeral and testamentary expenses, which presumably did not take place in England and Wales. Any wills made prior to his final marriage would have become invalid at that point, and he was already bankrupt by then.
Was he abroad because he was avoiding his creditors or were there other reasons for his travelling.
