Information gleaned from PHK's notes:
The Evening Dispatch Map of the early 1860s [click on map for greater detail] clearly shows this Terrace as being in Cleveland Street (51°31'19.73"N, 0°03'14.09"W). As a matter of fact, in 1865 Walkers Terrace was renamed (renumbered into) Cleveland Street, sometimes written Cleaveland Street, and previously called Red Cow Lane. Changes to street names were quite common in the nineteenth century. Cleveland Street was in Stepney, MEOT (Mile End Old Town). The area was obliterated during World War II and totally redeveloped.
When the JMK family left Cleveland Street in about 1832/33, JLK would have been only 14, Jane Charlotte Jr. only 11 and the youngest child only 2. So Walkers Terrace, JMK's London home after marriage (1818) ties in with Cleveland Street, but only while the children were quite young.
By the 1841 Census, the family were shown as living at East Side of the Green in Bethnal Green (51°31'40.96"N, 0°03'13.44"W) - at no. 7, according to the records of St. Georg's German Lutheran School, which was attended by two of the sons. This became Victoria Park Square, as it is today (actually a road, not a square), overlooking the attractive Bethnal Green Museum Gardens - or Bethnal Green. That census shows John Matthew and the six children (but not their mother Jane Charlotte), when the ages of the children range from 21 (JLK) down to 9. This seems appropriate to the story of musical parties, evening dress, and daughter Jane, the young hostess... then 18. One can imagine hearing the chords of the wind harp as the prevailing westerly breezes drifted across the Green into the window of no. 7.
Equally inconsistent with Walkers Terrace/Cleveland Street would seem to be the description we read in Clist Chapter 9 of JLK,...the young man in his father's house at Walkers Terrace... his love of horses, and his arrival at the front door with pony and trap - the first remembrance of him... by his future wife. . . Hardly a description of a 14-year-old. In short, it seems that G. E. Clist's interpretation of oral history made her associate the lifestyle of the young adults with the name Walkers Terrace, at a time when they were actually living in Bethnal Green in the terrace which included no. 7 East Side of the Green.
Furthermore, from Clist Chapter 1, it seems JLK's eldest daughter Fanny Adela Jane ("Addie"),...remembered the happy visits to this house [Walkers Terrace]...her grandfather [JMK]...and walks in the London parks...with Aunt Jane (the younger Jane Charlotte, JLK's sister), but Addie, who was born in 1848 could not have known Walkers Terrace in Cleveland Street. Indeed, she would have been under 3 at the time the family left the later house in Bethnal Green (at some time before the 1851 Census). So it seems likely that Addie's walks in the parks took place after JMK and the children had left Bethnal Green, perhaps near JLK's St. Pancras area, a stone's throw from Regents Park.
East Side of the Green (Victoria Park Square) has changed a good deal in the meantime. Nos. 1 to 11 (including JMK's no. 7) have been demolished, but at the northern end of that row of buildings, no. 15 still stands, as does no. 14, little changed perhaps; also 13 and 12, but with changed façades.The charming old houses of JMK's vintage still have an attractive view to the west overlooking the Green and, south-west, to St. John's Church, which was probably still being built when the family left some time between the censuses of 1841 and 1851.
This brings us to JMK's wife (and widow from 1857), Jane Charlotte née Prenton. She was living or staying in Bethnal Green away from the family (1851 and 1861 censuses and 1863 death certificate), in Great Somerford Street (approx. 51°31'22.39"N, 0°03'33.40"W) and Upper Suffolk Street.
In the 1851 census, JMK is living at 2 Clifton Place, South Hackney (approx. 51°32'07.43"N, 0°03'20.72"W). The household is made up of: John M. Kraushaar (head, widower, 53) Commercial Agent Ind Trade, born Trinity Parish, City of London; Jane Kraushaar (daur, unm, 25) born Stepney, Middlesex; William C. Kraushaar (son, unm, 24) Colonial Merchant's Clerk, born Stepney; Matthew Kraushaar (son, unm, 20) Colonial Merchant's Clerk, born Bethnal Green, Middlesex; Ann Hughes (servant, unm, 20) General Servant, born Hackney, Middlesex. So the question (destined to remain unanswered, one fears) is: why was JMK pretending to be a widower when his wife was living a mile down the road? (Not the kind of question Mrs Clist was likely to address...)
When JMK died in 1857, the certificate gave the place of death as 84 Cannon Street West, the J.M. Oppenheim office address after the moves from Basing Lane and Bow Lane in the City of London. It gave the same address for the residence of the witness or informant, his fourth son William Conrad. [This is at least possible, since Schröder employees sometimes lived on office premises.]
Still on Clist Chapter 1, we read that in Walkers Terrace, it was JLK's grandparents (JCK and Catherina Elizabeth) who gave the grandchildren their introduction to religion. JLK (born 1819), as early as age 5 remembered this influence. But in 1824, JLK could not have known his grandfather JCK, who had died in 1801. However, in JLK's book, he wrote about the grandmother in Lutheran simplicity... whom he particularly remembered. Catherine could well have been 10 or more years younger than her husband, so she COULD have been visiting Walkers Terrace in Cleveland Street around 1824, at 70+ years of age. If so, it could not be she who was buried under the name Caroline Elizabeth at Bunhill Fields in 1812, aged 61.
