Robert Larney had a older brother called Thomas born in 1885, who may also have died in WW1, are there any of his ancestors reading this who would know him?

My grandmother Emily Alexandra Dell(8 Knottisford Street Bethnal Green) got married to my Grandfather William Alexander Winter(14 Pott Street Bethnal Green). My grandma was a machinist and my grandad was a Plate Glass Slider. They were married on 25th December 1927. My grandma had two siblings a brother Frederick James Dell and a sister Amelia Louisa Dell. My mum has told me that Amelia Louise Dell was married to a gentleman called Joseph(Jack)Crump who was related to William Crump known as Harry Champion a music hall artist famous for songs such as Boiled Beef and carrots, Im Henry the 8th I am, Any old iron etc. I havent been able to discover so far how William and Joseph(Jack)Crump were related. Id love to have some imformation, Ive looked up Harry Champion on line and have found some basic things, but Id love to see some places where he performed, pictures, programmes reviews etc. On the internet it states he first apppeared in the Queens Poplar.

My mum Jean Alexandra Winter was born 3rd March 1931 at kingswood Forest Rise, has any one heard of this place or have any imformation?? On my mums birth certificate it states that the family lived at 62 Colville Road Leytonstone, although my mum thinks it was no 26!!!

My grandad served in WW2 in the Royal Navy, he was a chief Petty Officer and started as a Acting Joiner 4th Class 22nd June 1943 on HMS VICTORY and served on several ships, ending with HMS VICTORY joiner 3rd class on 11th June 1946. Does anyone remember my grandad or serve with him?

My mum married my dad George Andrew Potter(d.o.b 21.12.1929) on 2.6.1956 at St Elizabeths church Wood Lane Dagenham.
When my mum met my dad he told her that he was related to Don Cockell(the famous boxer who fought Rocky Marciano on 16th May 1955). Mum didnt take a lot of notice at the time, but when Ive researched Don Cockell it says that he was born in Battersea and his trade was Blacksmith, well my dad was also born in Battersea and his familys trade was also Blacksmith. My sister recalls my dad telling her that he was related to Don Cockell but she couldn't remember how. My dad died in 1995 and theres no one else I can ask. Does anyone have the answer to this, any imformation will be greatly appreciated.
