Hi
I checked for earlier wills. Unfortunately Samuel does not seem to have left a will (unless it is held at the Guildhall Library - but no Prerogative Court of Canterbury will or one in the lower church courts held at the LMA). Gloucestershire Record Office has an online database of wills - nothing showing there either that might be of help for the Tredington line.
Samuel's death certificate may give an indication of his occupation in life. There seems a connection in the family to 'office' work and therefore a reasonable standard of education. The Tredington line (3 male siblings at least including a half brother) you would expect might show something similar. Robert Eveness appears to sign with a cross on his marriage(s). Samuel of course could have been the sibling 'who made good' but as yet there is no evidence that this Samuel's baptism is connected to the man in St George in the East and no definite connection between him and the John who marries Ruth though that does look a strong possibility.

There is also this baptism which might be the first for Robert and Sarah

in which case this marriage becaomes a possibility
1st November 1770
Robert (X) Evans and Sarah (X) Russell both of this Parish were married in this Church by Banns in the Presence of Eliz: (X) Davison & William Tombs
http://freepages.genealogy.rootsweb.ancestry.com/~wrag44/tredington/tredington.htm There is no overlap in the register between Robert and Sarah Evans and Robert and Sarah Eveness. One 'arrives' in the registers in 1770 and disappears in them after the 1771 baptism. The first event for Robert and Sarah Eveness in the registers occurs with a baptism in 1773. Robert is a rare first name in Tredington.
