Hi Jasper,
I am sorry to be responding as tardily as this to your post of 1 December; I have been trying to do too many things at once (again)!
More on the Star of David rainwater hoppers in a moment. First, the interesting info you provided as "a little background" to your connection with the Goodharts. You mention work done on the family by Nicholas Goodhart (HCNG) -- presumably the man who was a senior officer in the Fleet Air Arm (now RN retd.) -- and you add "what would I have done without the internet?". That suggests that his research may be accessible online(?). If so, I would be fascinated to see it, and would appreciate a steer as to where one can find it.
You refer to Johann Heinrich Guthardt (whom I take to be identical with the man anglicised in
Hands Across the Sea as John Henry Goodhart). Is it thought that he remained in Germany, or did he join his sons in England? It would be interesting to learn whether any more is known about his dates and career, and whether some of his earlier ancestry has been proven. Presumably you or HCNG have seen the denization papers, and they were accurate in describing the family as natives of Borcken in Hesse-Cassel (or, in modern non-frenchified/anglicised terms, Borken in Hessen-Kassel).
I note here in passing
this link to a page on a German genealogical website about the Reuffurth family (unless newly placed online, perhaps familiar to you and/or HCNG); it mentions one Johann He(i)nrich Guthardt of Borken, cooper, formerly a soldier in the Cassel Lifeguard Regiment of Foot -- ?b. (or perhaps just "living") 1739 and m. 1765 an Anna Maria Krafft; he is shown as the son of another man of the same names (also a cooper), by Anna Barbara Cronenberger his wife. Rather oddly, the father is listed as having a brother with identical names but different dates, who was a brewer and town burgess. The two brothers (if they were indeed brothers) are in turn shown as children of a Nikolaus Guthardt, ?b. 1674. Not sure whether or how there could be any connection with the London sugar people; but some interesting coincidences of place and name. The sourcing is unclear.
Now, those Stars of David. Initially they did strike me -- as apparently you too -- as potentially relevant evidence about the hypothesised Jewish descent of the Goodharts. But for that potential relevance even to exist we would need to be confident that the Goodharts were the people who actually erected the rainwater hoppers and (presumably) selected the design. On closer examination of the evidence accessible via the internet, I very much doubt that they were. It looks as though the house concerned was Langley
Court, not the much older Langley
Park. Langley Court was built in the mid-1880s by the Bucknall family on the site of Langley Farm, a house that they had bought from the Goodharts in 1884 and which they had promptly demolished to make way for a successor.
So far as I can tell from online sources, the Goodharts probably closed up Langley Park soon after Charles Emanuel's death in 1903, and then sold it to developers in 1908; so they were out of the picture by the time the big house burned in 1913.
I have set out fuller details about the evidence in the next pair of messages. See what you think. Per
this Familytreemaker pedigree about the Bucknall family, they too seem to have no obviously Jewish ancestry -- so those Stars of David (assuming that they were in fact there at all) may simply have been a chance decorative feature designed in by the architect. One also needs to bear in mind that the "double triangle" only really achieved general recognition as a uniquely Jewish symbol early in the 20th century.
