Is this Thomas Weston Sr. or Jr. (2nd son)
Sr. died on 9th May 1901

I assume these items belong to Thomas Weston Sr .. we need a birth date so I could trace him properly.
T.R. Weston was listed as a correspondent in Bristol in 1874 so I assume he was of same generation?
Unless I'm confused, I thought John Weston, who lives not far from me, and is well into his nineties, is a descendent.
