Pete,
I have just googled "Edward Bough Windsor" and found your post from back in 2007.
I don't know how far you have progressed with your search for your grandad? I have been researching the family of my partner (a Bough) for years now, his father was the youngest brother of your grandad.
Your father's birth certificate states parents as Edward Samuel Bough, general dealer and Harriet Bough, formerly Hammond. Edward Bough was born in Lambeth on 13 July 1859, and his birth was registered as "Samuel Bough". Still using the name Samuel, he married Harriet Hammond on 1 June 1879 in Lambeth.
In the 1881 Census, Samuel and Harriet are in Southwark (RG11 0521. F 127 p 27).
At some point they moved to Berkshire and had the following children:
Harriet Agnes, birth reg 1886 June - Cookham 2c 430
Edward Samuel, birth reg 1888 June - Cookham 2c 404
Thomas, born 21 June 1890, birth reg 1890 June - Cookham
John Robert, birth reg 1893 June - Cookham 2c 420
George Spencer, birth reg 1895 March - Cookham 22 425
Victoria Diamond Jubilee, born 7 April 1897 - Windsor
John born 11 December 1900, birth reg 1901 March - Windsor
The family were living in Maidenhead when the Cookham births were registered and in Windsor when the Windsor births were registered.
From the three certificates I bought, it seems that Samuel began to use Edward as a second name and finally, dropped the "Samuel" altogether by the time Victoria and John were born in Windsor, just calling himself Edward Bough.
From the postings back in 2007, you will have seen that the family was split up in the 1901 Census. Edward's wife, Harriet died later that year, on 30 October 1901 so maybe she was poorly at the time of the Census. I have never been able to trace Edward's death, although I was told by my partner's mother that he died when John was at a very young age.
Now the 1911 Census is here and I can find only three of the seven children!
John was at Mayford Industrial School in Surrey, Agnes (obviously dropped the Harriet) was in St Pancras, London and Edward "military" was in Alton, Hampshire.
Where are the other four? I'm unsure from your earlier posting whether your grandfather emigrated to Australia and died there or whether he died in England?
Sorry for the length of the posting. I look forward to hearing from you.
Nina
