Think I might be distantly related to you. I come from a line of Jemsons that has its origins in Lancashire around the town of Fleetwood. My great Grandfather John Jemson farmed in the area and made enough money in the First World War to send two of his children to Medical School at Guys Hospital in London -they were James Jemson (my namesake) and Betty aka Bessie Jemson. My father John Jemson also went to Guys and emigrated to Canada in 1957. I was born in Ramsgate Kent when my father was in the RAF doing his National, but have lived in New Zealand since 1987 as I am married to a Kiwi.
I am just getting started in this area and would like to haer from anybody with further info as Jemson is an unusual surname - when I was growning up in rural Canada, I never met anyone with the same name until I went to England for a holiday when I was seven - it was a bit of a weird expereince!
Looking forward to hearing from you
