Flora Liebe 1897-1956 m 1922 as his 3 w Sir Gerald Stanhope HANSON 2 Bt 1867-1946 and was the mother (not the wife) of the 4 & final Bt mentioned above. She was d of Lt-Col William Arthur BLENNERHASSETT 1869- of Clifton, Bristol [by his 11 July 1892 m (St Catherine, Jamaica) to Mabel Annie WILLIAMS].
There is a W A Blennerhassett in the Irish gentry family of that name (see attached) but his details don't match with the above, although there is a Jamaica connection.
That’s all I have time for I’m afraid, but hopefully may prompt others to post more info.
