Hi Alan and Jean,
Yes I've got all those but thank you for taking an interest
Henry Royall Minns (father) was the one who took out all the patents. The family spent a few years in Quebec returning in May 1877 and they were all back home in England in 1881. Son Henry Benjamin Royall Minns was in London for the 1891 census and then he and his wife disappear, son Jesse Royall is not to be found after 1881 and son John Royall emigrated to the US & later Puerto Rico (via Australia and The Falkland Islands )where he and all his descendants became Royallminns!
Henry's five daughters were a little easier to track - my gt grandmother being one of them!
I had hoped that HBR Minns had been travelling to Quebec
after 1891 and therefore solving my problem with him. Instead as is usual (

) it leads to more questions: why did he go, how long did he stay?
HBR actually married in London in July 1883 to a lady who admiited to being 3 years older than him but who was actually 12!
Anyway many thanks both of you .....and if you do happen to spot anything else......!
Best wishes,
Meg
