1907: England & Wales National Probate Calendar:

<Births.

On the 17th inst, at 42 Elgin Crescent, Kensington Park, the wife of Francis Edward Greenaway, Esq., of a son, stillborn.>

When did the family move from #42 to #75?

<Elgin Crescent runs from Portobello Road west across Ladbroke Grove and then curls round to the south to join Clarendon Road. East of Ladbroke Grove, it was originally called Elgin Road. West of Ladbroke Grove, it was originally numbered from 1-36 consecutive on the northern side, starting at the western end (so the present No. 120 was No. 1) and from 37-81 consecutive on the southern side starting at the eastern end (so the present No. 63 was No. 37). The street was officially renumbered in 1880.>

<In April 1874 Staunton's financial circumstances compelled him to move to cheaper accommodation. [...]

He and his wife moved into lodgings, and when he next wrote, on 9 April 1874, it was to give his new address, which is only a few hundred yards away [from Landsdowne Road], at 29 Elgin Road, Kensington Park. [...]

Some insight into the living conditions in his new lodgings is offered by an undated letter written at some stage during his time at 29 Elgin Road. In it he complains of "a severe attack of (I think) bronchitis attributable to the infernal state of the drainage". He felt he was being poisoned at night by the stenches from a privy and a drain opening just below his nose. The former was open all day and night for the convenience of the seven people who formed the household, and within a foot of the privy stood the larder, with both doors open. "I have had a narrow escape - a run away knock at Death's door...">

Within a few weeks, he was indeed dead.

I was wrong. It is the same property, so Greenaway must have lived there continuously from on or about the time of his marriage in 1859 to his death.

I hadn't appreciated at first the 1880 change was from consecutive numbering to that of odd and even. My field trip there today confirmed the matter. Swanky street; BoJo used to live there.
