Just by chance in a different internet search, I stumbled across this set of exchanges. I haven't read through all of them yet, but I'm so surprised to find them, that I'm responding straight away.
Sarah Bower was, I assume, the daughter of the very powerful Bower family who had a big bottling business in Hunslet (there until the 1960's).
In 1968, I used to deliver evening papers and would walk home through Hunslet cemetery. I was very taken by the grave of Horatio and Sarah Wood - which - as far as I can remember was rather grand, and had iron railings around it. What struck me also was that it had Horatio and Sarah's names in gothic script, and mentioned that he was a solicitor. I was also intrigued by the fact that they died on the same day. Even as a 14 year old, I thought that the coincidence must be due to them having died in the cholera epidemic.
When I visited the cemetary again in 1973, I was astonished to find that the grave had gone. (There are still a lot of other Bower graves there, however.) So Horatio has stayed in my mind ever since.
Many years later when back in Leeds, I researched Horatio in Leeds central Library. He voted in the general elections and his voting preferences are recorded. He was man of some means, and in addition to his legal practice, had a counting house down near the river
Horatio's legal business was in Bowers Yard - which is off Briggate in the city centre. I went there in 1999, and I suspect that the office he had is still there - though obviously the place has changed...I even went up to the Ellersby Road area in east Leeds where Hill House Place used to be.
Some years after this, when I became computer literate, I did an internet search for Horatio, and found that - unless there was another solicitor called Horatio Wood in Leeds at the time ( which seems wildly improbable) - he was a political radical having beeing elected as a Chartist representative to the Leeds Improvement Commission in 1841. I think his radicalism must have subsided somewhat, as, in the last general election he voted in, he gave votes to the Tory and Whig candidates (if I remember rightly).
Another net search some years later, indicated that he might have lived (after Hill House Place) at a grand house called Holbeck Lodge with central heating that was designed by the engineer matthew Murray. I'm not sure, however, whether this Holbeck Lodge is the same one as he was living in at the time of his death. Whatever, even though the building has been long demolished, there is a photo of the Matthew Murray Holbeck Lodge on the Leodis photographic archive (which is free, and fully accessible on-line).
As I'm not related in any way to this family, I haven't taken the research any further. I imagine that there must be archive material about the Leeds Improvement Commissioners. The only other thing I recall, is that a Horatio Wood was a member of the 'Leeds Philosophical and (something else)' society.
I think I also found that the Woods were buried in unconsecrated ground (maybe because they wanted them buried fast). This might explain why their grave was given the chop when others were left intact...
Hope these recollections are of interest.
