My great grandfather was William George Thomas Doling born c1887/8 New Cross, Deptford.
You say William John died in 1905, it would fit him working in the dockyard (as William George did) but i believe he was a grocer, also i was told by a relative she remembers William John and she was born in 1926, i appreciate people can get things wrong though. Could you give me more info on what you have of this family?
William had 9 siblings that i am aware of -
William John b New cross c1879/80, Alice c1881, Lily Maud 1883, Albert 1885 Walter Henry 1888, Lucy 1890, Florence May 1892, Minnie Eliza 1895 and Mabel Ada 1896 also died that year.
Their parents were William Doling and Alice Heath. Do you have this? From what i have seen your Richard may have been born in 1903 Woolwich. I also see there is a William John Doling born in Medway in the 1860's. Also a Vera born Medway 1905. I can't see that they are the same family. My Doling's originally come from Southampton.
Many regards
