Hi, Everyone,
Just a postscript on this lively and entertaining thread (while it lasted) in that I've had a look on the ScottishPeoples website at their newly-up-and-running 1861 Census. I've paid my Scottish pounds to discover for the first time that James Greaves Dyson had a half-brother called Thomas Dyson born in Innellan, near Dunoon, Argyllshire in 1849/50.
HE must surely be the witness at his half-brother's wedding in 1871, and as I hadn't put in the "Born in Scotland" element when I searched the 1881 English Census, he wasn't in the short-list.
However, some good family history was unearthed on this thread, even if it was the wrong Thomas...
Thanks for all those contributions, nevertheless,
Keith
