Thank you folks for the various responses.
I know Henry's precise birthdate of 4th June, 1880.
I have access to 1911 census records, but have found neither Henry or his ship HMS Mercury for that date.
His 2nd marriage was in Edinburgh to Alexandrina Goodwin and he died there in March 1938, the death being registered by the said 2nd wife.
Is there some conclusive evidence that jane Elizabeth Widgery married Albert Edward, the BMD record quotes Henry Webber as a possible spouse also.
Regards,
John
