The Charles Ivory is I beleieve the same Charles Ivory who lived at Ham Farm, Faversham and later lived at 21 Brogdale Road, Faversham. He died 1921 and his wife Olive who died in 1892 are buried at Davington Churchyard, where the headstone is still there.Charles was the son of William Ivory a farmer from Newington and his wife Ann Hughes.
I do know that William James Ivory died in August 1901 after being crushed by an Electric car he was driving. He is buried at Sittingbourne cemetry.I have a copy of the death cert ordered by mistake. William James name is given as Rossiter so this must be the same.
Hope this helps and if you need any more help, please let me know.
