My Grandfather Victor Frank Dempsey was born Auberon St Silvertown 1919 his parents were Eleanor Hart and Owen Dempsey. Have a fair bit of information on his mother Eleanor (who was previously married to Charles Adair Rennie before marrying Owen Dempsey in March 1918. Woolwich
Eleanor parents, Thomas Alexander Hart and Elizabeth Cornforth ran the Mariner's Arms on Albert Rd. Her sister Matilda married Albert George Pope, a lot of the Popes worked for the Keillers. Thomas Alexander Hart's father was John Alexander Fustic Hart and he was a Mulatto born in Jamaica 1774, would love to find out more on this branch also. Thomas was born in Gloucester 1830
Charles Adair Rennie's father was John McDonald Rennie born Marylebone abt 1829, am unsure if any connection to the John Rennie who had something to do with London Bridge, I can't find John on any census's before 1871.
The main person I'm looking for information on is Owen Dempsey, his name may also be Harold Owen Dempsey or Henry Owen Dempsey, think he was born about 1876. According to Eleanor and Owen's marriage certificate his fathers name was Richard Henry Dempsey who worked WBC I am guessing this may be Woolwich Borough Council?

Owen served in WW1 both in RFA and AVC (British Army Veterinary Corps)
We know nothing else on him and would like to find out more if possible.
My Grandfather never knew his father Owen as after my grandfathers mother, Eleanor died in 1921 when my grandfather was only about 2 and a half his father cleared out and as far as I am aware my grandfather never saw him again :-( My Grandfather was raised by his mother's sister Matilda Pope (nee Hart)
If any one knows anything of Owen Dempsey I'd love to hear from you, I have tried to find him on census's but nothing, have found a few but am fairly certain they are not him.
Or if any names ring a bell I am happy to swap info
