Wow, thank you very much. Lots of fascinating stuff there.
Makes me even more determined to find out where the family came from.
I think you are probably right about Frances, I think his son became quite eminent.
I will try the library department as suggested.
I have also reached out to the Halton Hills Library where Walter Lewis who wrote the entry used to work.
They have yet to get back to me.
Unfortunately John and Frances are fairly common names in the Leys family, but perhaps if I try cross referencing them I will come up with something.
I will update if I do.
Thanks again for info and suggestions to RunKitty and DianaCanada
PS Unfortunately I am in Sunny Edinburgh, Scotland so remote research a bit tricky!
