Harry married Emelie in 1918 and by the laws of the time, she automatically became a US citizen, and never had to apply in her own right. At the 1940 census Emelie (now Emily) and Harry lived in South Boston on East Fifth St.; Harry worked as a driver for a coal company. In their household was their son, Harry, Jr. aged 12, and Emily's widowed son, Oscar Bruynell (here confusingly called Harry's "son-in-law" and named Oscar "Brown").
Harry, died of heart disease in November 1963 while living at 48 Newport St. in Dorchester.
Note: I'm guessing Harry's dad must have had the same problems and some snickers with his name both in London and here in Boston. Even back at the turn of the century when you would think there may have been a little more decorum. Harry 's family must have some stories to tell if they were here today.
