What we think is that Albert Henry died in 1919 or thereabouts from 'flu (epidemic year?) in USA.His wife is known in family history as Beatrice Wallace - but that could have been an alias... so Heileman is possible.We know nothing of her - AH had gone to USA with another woman.
AH and wife had one son - Raymond Lawrence Chislett, we think born Putney in 1907.
Winfield - we think - was added to the surname by AH and his new woman while in US!
Thanks for your help so far - as I have passed it on to my parents - both in their 70s - other pieces get remembered.
