From the Kentish Mercury 3rd August 1883. This Tabard Road appears to have been in Bow, so can't be the Borough one? Bow is certainly nearer to Whitechapel? There's a Wickham Close near Stepney Green, has this been renamed from Wickham Place? Could this be where Tabard Street was??
There was a Tabard Court which was just south of Bow in Lodore Street E14 (Poplar). Its location is now taken by the St Frideswides Mission, which was the real location for the TV series Call The Midwife, although the nuns left it to go to the midlands in the 60s.
Wickham Close is a new road (1999)named after the tower block that used to be there called Wickham House which was named after a place in Sussex, Wickham Green.
