We've just had a couple of e-mails from Ken Joyal in Canada, whose wife Lesley is descended from Charles William Pearson (brother to Val's great-grandfather Daniel William Pearson).
Lesley is descended from Olive Lois Pearson, daughter of Charles William Pearson, and there is some mystery about her date of death, and the circumstances of her death. Ken wondered if it could have been an accident. We have a note that she was dead before 1928, but I'm not sure where we got that information -- will need to check on it.
Olive Lois also had a brother Francis Muncaster (Frank) Pearson, who was a journalist in Canada, but we haven't been able to find out much about him.
Charles William Pearson is another one who probably deserves a Wikipedia article. He was a pioneer Anglican missionary in Uganda, but returned to England because of ill-health. He got to Uganda by sailing up the Nile, which was quite an adventurous journey in those days. Actually if you look at my Blogger profile here you will see that one of my favourite films is Sammy going south, which is based on a novel of the same name, about a boy whose parents were killed in the Anglo-French bombing of Egypt in 1956, and makes a journey over more or less the same route, and makes it possible to picture C.W. Pearson's journey 70 years earlier, though I'm not sure if it was all filmed on location in Sudan.
Another of the Pearson brothers also had an interesting life and an obscure death. That was John Johnson Pearson, who was a British Israelite, and travelled to India at one point, and around the "prophetic earth" -- the Near and Middle East. Mad Uncle Anthony told us he lived in Paris with a harem of Sikh ladies, but I think that needs to be taken with several sacks of salt.
I suppose the best way of finding out what happened to Olive would be to search for her death certificate, but it's an awkward period. The FreeBMD indexes only go up to 1910 or thereabouts, and while indexes after about 1970 are available easily, 1923-28 falls in between.
